When you talk about things "not simply poofing out of existence" what you're really describing is like a conservation law. Out of the countless photons that strike an object (say, a table) kept inside the room, some will get absorbed, while others will get reflected and lose a certain amount of energy in the process. @Jimmy360 Trying not to be confusing is a great goal. The next association could easily come from something else entirely! Why can't standing waves on a pond, like on a gutar, have any aplitude at the wavelength required to fit? In other words, the kinetic energy of the photon is converted to potential energy (the electron has higher potential energy in the higher excited state). When you turn on a lightbulb, you easily create many photons. If you peep inside a lamp or a tube light, you wouldnt find a hidden army of uncountable photons ready to ambush on the switchs command. Would it be possible to build a powerless holographic projector? Use MathJax to format equations. This happens for example at linear particle accelerators. And I think that's natural as well. I think that's natural. Reddit and its partners use cookies and similar technologies to provide you with a better experience. A photon of the same energy will be able to kick the electron to the higher energy level, disappearing in the process. http://en.m.wikipedia.org/wiki/Noether%27s_theorem, CEO Update: Paving the road forward with AI and community at the center, Building a safer community: Announcing our new Code of Conduct, AI/ML Tool examples part 3 - Title-Drafting Assistant, We are graduating the updated button styling for vote arrows, Physics.SE remains a site by humans, for humans. It's my understanding that photons are sort of "ripples" in space time, or electromagnetic spectrum, but this premise is probably not completely correct. When you turn on the lights where does the energy come from? Do All Photons In The World Move At The Same Speed? Whatever it is, you can see it being blown around in the slow-mo when he let's air back in. @aandreev I find all this quantum stuff hard to believe. Enamored with science ever since discovering a picture book about Saturn at the age of 7, he believes that what fundamentally fuels this passion is his curiosity and appetite for wonder. The photons presumably came from somewhere in the history of the formation of the black hole or in the accretion disc, but undergo countless interactions with parts of the black hole so when they finally escape, we have no idea what process generated them. However, if you were to peek inside an atom, would you find a hidden army of uncountable photons, ready to ambush on the electrons command? The wording suggests to me that you're expecting some properties to be conserved, i.e. It's so unlike everything I've learned, where none of its rules seem to apply, and I find it extremely hard to believe. As if to say, if the particles could ever reach absolute zero, they'd stop dancing on the water and the pond would be still? A real rug has a small amount of elasticity and can slide against the wood floor. Solution 1. What symmetry the conservation of excess area comes from, I'm not sure. Regulations regarding taking off across the runway, Negative R2 on Simple Linear Regression (with intercept). The electron is a point particle in this theory. The total impulse is still conserved; the two impulses add up to exactly zero. I've heard the "where does your lap go" question before, but only as a joke. Your intuition that things aren't just "poofed" out of existence is probably due to your everyday experience that objects generally can be broken into parts, but not usually destroyed. They do disappear (more on this in a second). Why doesn't a changed particle ever lose energy by interacting with others by radiation of virtual photons? Is there a "difference" between photons that act as virtual particles and photons that act as the quanta of EM radiation? } How appropriate is it to post a tweet saying that I am looking for postdoc positions? the underlying floor) is a conserved quantity, that only fails to be conserved on the boundaries of the carpet. 2023 Physics Forums, All Rights Reserved, Exploring Particle/Wave Duality in Photons. They are emitted by atoms with many electrons, such as those high in the periodic table. To understand where photons come from, let's take a closer look at the atom: In the center of every atom is a tiny, dense nucleus. edited 11 yr. ago. And burning gives both heat and light. Virtual particles are fictitious , they are a variable mathematical expression, not measurable in any sense. Do photons of different energies interact with each other? (And I probably shouldn't mention it here either). How to deal with "online" status competition at work? To paraphrase the question -, @Jimmy360 Trying not to be confusing is a great goal. There is a chance to imagine how the photon goes over to the electron. What happens to the absorbed colour on an object? Archived post. http://en.m.wikipedia.org/wiki/Noether%27s_theorem. It is the basic unit of all light. Instead of placing the filament in a jar which was evacuated, I placed it under liquid nitrogen and turned the juice on. If they are virtual photons emitted by the charged particles, it does not make sense for them to have infinite range (uncertainty theorem). Scientific discovery can be unexpected and full of chance surprises. is the process that creates lower energy photons (moving between energy levels) the same that creates high energy photons such as gamma rays, or is there two processes at work here? The best answers are voted up and rise to the top, Not the answer you're looking for? When that energy is created, part of the energy of the interacting charges is simultaneously destroyed to compensate. Photons are created when electrons make a downward transition because that is how quantum electrodynamics works, at least in this universe. A model construct. Standing in a lake, I can make a ripple in the water by moving my hand. Do we know why the field produced by charge extends to infinity? In addition, photons can be split into multiple lower-energy photons, and the energyof a photon can be increasedby, for example, bouncing it off of a moving mirror. Virtual particles are fictitious , they are a variable mathematical expression, not measurable in any sense. True. 9,988 views Jan 27, 2009 86 Dislike Share eHow 884K subscribers Photons come from electrons that fall from one energy level to another, creating small packets of energy of distinct energy types.. Alternatively, they are very high-energy photons. To learn more, see our tips on writing great answers. The best black body is a black hole. Physics claims the infinity of the electric field of electrons and the other charged particles. If there were an inside as the one you propose, the standard model would not work as well as it does. 2023 Physics Forums, All Rights Reserved, https://math.ucr.edu/home/baez/physics/Relativity/SR/experiments.html#Tests_of_the_poR, Exploring Particle/Wave Duality in Photons. HOWEVER, this sort of thing is fluff; it doesn't really have a proper meaning (the only real meaning is the mathematics) and this particular interpretation is not conventional, so it would not be a good idea to mention it to your teacher. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. No, physics is not about fairness but of consistency of mathematical models with data. Noise cancels but variance sums - contradiction? I didn't want my answer to be confusing to him/her. It is a concise and direct answer to a specific question about a specific aspect of physics. Don't know why this is in Relativity. You still have all the normal emission processes going on: spontaneous emission, stimulated emission, annihilation, etc-- which add up to the black body emission. X rays are electromagnetic waves of very short wavelength. A photon really is just a way of looking at disturbances/excitations in the electric field, and so its "destruction" just represents that energy that was present in the field has been moved into some other mode. } Powered by SiteManager | Contact Webmaster. A photon definitely has energy, but your gamma photon was created by a nuclear process. Leaps to a space outside this range, whether larger or smaller, will produce photons that are invisible. Don't know why this is in Relativity. Where do they go when they dissipate? "It means that photons can be created and destroyed." An accelerating charged particle generates photons tangentially as well as a decelarating one. the underlying floor) is a conserved quantity, that only fails to be conserved on the boundaries of the carpet. Now, can the photon disappear? Where do the infrared light photons come from? Does substituting electrons with muons change the atomic shell configuration? Interesting to think about, there is excess in two different dimensions: a perfect canal-soluton can't be pushed off the long edges, even though they are very close always. A photon really is just a way of looking at disturbances/excitations in the electric field, and so its "destruction" just represents that energy that was present in the field has been moved into some other mode. In quantum field theory, the field (the pond surface) is everywhere, and it may become excited (throwing a stone in). The nature of my question speaks for itself that I don't know much about physics. Are all virtual photons exchanged? Physics So take any light bulb for example, when turned on the electron flow heats the filament of the bulb which gives out photons we perceive as light. Yes, photons carry energy. And the most important point is that all the photons (of different energy) are made from this two quanta too. A photon of the same energy will be able to kick the electron to the higher energy level, disappearing in the process. What one-octave set of notes is most comfortable for an SATB choir to sing in unison/octaves? color: #151515; They are only a Gedankenexperiment because until now the electromagnetic spectrum seems to be continuous and there is no evidence for quantisation. I guess, it may by a silly question, but why fire (I mean flame) is bright? 11,161 Looks cool. Can I also say: 'ich tut mir leid' instead of 'es tut mir leid'? Standing waves don't have laps; sitting waves do. } And now please forget about this two quanta. In particular a stationary particle would not . So is the case with the radio waves transmitted and received by our phones. That is, the best known theory (Standard Model) for photon interactions could be interpreted in that way without changing the mathematics. Light is an electromagnetic wave. How is the EM force exchanged over long distances? PSA: This answer may be blatantly wrong, but it is an attempt to answer the question. Whether or not photoemission takes place depends on: the energy of the photon. Can gamma radiation cause elements to become radioactive? color: #151515; For example virtual photons can travel faster than light. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Here are some examples. Think of waves on a pond. That's actually a very good analogy in some ways because the math that describes transverse waves is the same, but different in a very fundamental way: the waves are quantized. What happens if a manifested instant gets blinked? When you turn on a lightbulb, you easily create many photons. The 26-year-old will at least know what to expect from Gauff, having faced her in Florida on national team duty back in April - although how much she learned from a 6-1 6-3 defeat is unclear. This literally is nuclear energy; the original atom nucleus had a higher energy than the resulting nucleus. Could you explain it more simply and avoid using so much jargon? Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. The lump is not a "thing" but a "state". (And I probably shouldn't mention it here either). How is "the photon disappears and is absorbed as heat energy" any different from "the photon turns into something"? To me it appears as though they just appear from nowhere. Standing waves don't have laps; sitting waves do. The energy carried by that photon has to be accounted for, as does its momentum and angular momentum. Why Do People Indulge In Extreme And Dangerous Sports? #fca_qc_quiz_63474.fca_qc_quiz button.fca_qc_next_question:hover { You're more likely to get authoritative answers in one of the engineering forums. Akash Peshin is an Electronic Engineer from the University of Mumbai, India and a science writer at ScienceABC. Artificial abstractions are an effective way of structuring learned knowledge, but an ineffective way of communicating new concepts. Electrons reside inside atoms in different energy levels. "OK, so photons. A spring, a rubber band, water on top of a waterfall, these are all examples of potential energy. If an electron is a fundamental particle how can it release photons. It begs the question of. ScienceABC participates in the Amazon Associates Program, affiliate advertising program designed to provide a means Can I infer that Schrdinger's cat is dead without opening the box, if I wait a thousand years? That helps support ScienceABC with some money to maintain the site. border: #151515 0px solid; #fca_qc_quiz_63474.fca_qc_quiz span.fca_qc_answer_span { Alongside with some electrodynamics and quantum mechanics to understand what photon is (not). When cosmic raysvery high-energy charged particlesstrike the gas clouds, or interact with the visible light from the stars, they produce a sea of high-energy photons. Minimize is returning unevaluated for a simple positive integer domain problem. The short answer is yes. This is due to Noether's Theorem. The best answers are voted up and rise to the top, Not the answer you're looking for? :-). How can an accidental cat scratch break skin but not damage clothes? @CommaToast The standard model is called standard model because it fits with great accuracy a huge number of measurements, and predicts future measurements too, as has been seen at LHC. And this concept - under the presumption that field lines exist and this field lines are made from this two quanta in clusters with continuous changing numbers - allows to show that the attraction of the electron and the proton in the atom has discrete limits. You got {{SCORE_CORRECT}} out of {{SCORE_TOTAL}}, Quantum Physics: Heres Why Movies Always Get It Wrong, How are photons created and destroyed? See the wikipedia page for for more.). Do the actual physical thermal vibrations of charged particles "jiggle" the EM field around them? As long as the lamp is glowing, the room will have a constant supply of photons. Why Are Infrared Waves Associated With Heat? Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. Where do they "come from" when you throw a stone in? There are more conserved quantities, but in the end the conclusion is simple: a photon is just a particle with a few properties, and all those individual properties can be accounted for. If they are energy packets radiated by the charged particle, where does this energy come from and why is it not depleted? Another source of photons is from various particle interactions; as particles are destroyed or created, photons can be released as by-products. But I find it hard to believe that the photon simply "disappears." Assume you have only one hydrogen atom. Secondarily, if photons are massless, how do they interact with other particles and experience stuff such as refraction? Where do these photons come from? But photons come out of electrons in experiments all the time can you prove they don't? Photons are created by charges changing orbital state, or being accelerated. The best answers are voted up and rise to the top, Not the answer you're looking for? Where do the electron and positrons go? Where do the photons mediating the electromagnetic force come from? The Feynmann diagrams you've undoubtably seen are just a graphical representation of a calculation not a literal exchange of a particle. Why are radicals so intolerant of slight deviations in doctrine? In Germany, does an academic position after PhD have an age limit? "Because photons have no number that must be conserved." @CommaToast The standard model is called standard model because it fits with great accuracy a huge number of measurements, and predicts future measurements too, as has been seen at LHC. Is The African Continent Splitting In Two? A luminiferous aether that is comprised of particles that are a magnetic analogue of electric matter. Because anything moving at c experiences no time, and something not experiencing time makes quantum weirdness much easier to reconcile. From the energy carried by the electron. Because it turned into something else, it's not a photon, so the photon did disappear. They do disappear (more on this in a second). Do virtual mesons exchanged between nucleons in the nuclear force ever decay before reaching the recipient nucleon? When a electron gains a certain amount of energy then it jumps to a higher energy orbit unless it has absorbed so much energy that its ejected, it again comes back to its original orbit after losing the energy i.e emitting it in form of Electro-magnetic . Your intuition that things aren't just "poofed" out of existence is probably due to your everyday experience that objects generally can be broken into parts, but not usually destroyed. There is no inside. This is due to Noether's Theorem. The lump is not a "thing" but a "state". A photon is not, If you prefer, it wouldn't be too wrong to think of an electric charge as a hole in the universe into which photons may disappear, or out of which photons may appear. The filament glowed happily as long as it was submerged although the LN. This type of interactions of electrons and ions with fields happens in the photsphere of the sun, for example, generating the light spectrum we observe. Can I takeoff as VFR from class G with 2sm vis. A photon is not, If you prefer, it wouldn't be too wrong to think of an electric charge as a hole in the universe into which photons may disappear, or out of which photons may appear. and our JavaScript is disabled. For instance, we say that energy is neither created nor destroyed. Dalton, Rutherford, Bohr and Heisenberg Models Explained. The short answer is yes. You'll see the resulting nucleus recoil after emitting a gamma photon - it gets an impulse change in the opposite direction. That is, the best known theory (Standard Model) for photon interactions could be interpreted in that way without changing the mathematics. Learn more about Stack Overflow the company, and our products. As millions and billions of electrons simultaneously descend to lower levels, the tungsten unleashes a massive torrent of photons. On a slightly deeper level, it was created from the energy in the muscles that moved my hand, which came from the food I ate earlier. How do we see? I'd hesitate to say they turn into "heat energy," both because we don't use the term "heat" that way in a technical sense and because most of the time we like to talk about atoms absorbing photons. So, light or a photon is produced when an electron transitions from a higher energy level to a lower energy level. You can also correlate it to the photo electric effect, in which the energy( the photon) is absorbed by the electrons(? That way watching TV feels liberating :P, This is a terrible answer, and a terrible way to teach physics. A spring, a rubber band, water on top of a waterfall, these are all examples of potential energy. If photons can't escape a black hole, how come gravitons can? Where Do Photons Go When A Light Source Is Turned Off? The result is the instantaneous creation of a photon; it literally pops into existence out of sheer nothing, whatever that is. A real rug has a small amount of elasticity and can slide against the wood floor. For more information, please see our When an electron drops from one orbit to a lower orbit, it secretes a photon. typically be in some state other than the ground (stable) state. They do disappear (more on this in a second). @dmckee The interaction electron <-> photon is always accompanied by an secondary emission of photon(s) from the excited electron. Is it possible to raise the frequency of command input to the processor in this way? #fca_qc_quiz_63474.fca_qc_quiz div.fca_qc_answer_div:active { This in turn might suggest a longitudinal wave in the luminiferous aether. Red cones absorb most of the red light, but very little green light, and almost no blue light. These photons of energy are trapped inside the star and have to get out. Would sending audio fragments over a phone call be considered a form of cryptology? As if to say, if the particles could ever reach absolute zero, they'd stop dancing on the water and the pond would be still? Here are some examples. How is "the photon disappears and is absorbed as heat energy" any different from "the photon turns into something"? This vibration is a form of kinetic energy. Black body radiation can't possibly be caused by electrons dropping orbits, because there are only so many electron orbits, and bodies can emit black body radiation for a really long time. There are three kinds of cone, roughly corresponding to red, green, and blue. set of spectrum lines, just as atomic (electron orbital) energy levels do. Whether the light produced will be visible or invisible depends on the electromagnetic waves frequency or the energy of the photon. While it is true, as exemplified by stars, it is inefficient. Why are radicals so intolerant of slight deviations in doctrine? Where does the light go when I turn off the light switch? Where does an electromagnetic wave's energy come from? Now we have hints that some neutrinos likely come from tidal disruption events, but there's a lot more unexplained neutrino flux to go around. The leaps the electronsthat produce these photons make arent large enough. Where do photons go when they are absorbed? (P.S.. PSA: This answer may be blatantly wrong, but it is an attempt to answer the question. This appearing and disappearing is not an attribute of photons only. Where do photons come from, or how are they "created"? "It means that photons can be created and destroyed." How to add a local CA authority on an air-gapped host of Debian. (Photo Credit: Pixabay). I'm pretty sure the lumpiness of a carpet (excess area w.r.t. Because it turned into something else, it's not a photon, so the photon did disappear. background-color: #dbdbdb; This is a terrible answer, and a terrible way to teach physics. Where do the incident photons come from? Looks cool. Written by Akash Peshin Last Updated On: 8 Jul 2022 Table of Contents (click to expand) The photons produced by a source of light come from the energy created when an electron transitions from a higher energy level to a lower energy level. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. "How can photons just poof out of existence?" Why do universities check for plagiarism in student assignments with online content? Also, if heated objects do emit light, why are humans and other warm-blooded animals so difficult to find in a completely dark room? A photon, unlike some other particles, has no number that must be conserved, thus when absorbed all of the energy present goes into exciting the particle which absorbed it, allowing no laws to be broken. Clearly photons do have energy. Can a gamma ray or x-ray cause an isotope change of a nucleus with all its electrons stripped away? Where does a lump in a hall carpet go if you manage to stomp it out rather then shift it? 1 Introduction Earlier this year, an unidenti ed spectral line at 3.55-3.57 keV was reported by Bulbul et al. Common sense tells me it must turn into something or other, not just simply poof out of existence; then again, common sense has betrayed me before. To excite the electric field, which then excites the magnetic field (according to Maxwells laws), which re-excites the electric field and so on, we must first excite, as the fields name suggests, electrons! The force between the electrons is indeed mediated by the photon quantum field, but it's not literally an exchange of virtual photons. This reasoning is incomplete. For this one need two different quanta, one of them is on the end of the electrons and the antiprotons electric fields and one quanta, which is on the end of the positrons and the protons electric fields. In the case of visible photons, the charged particle is usually an electron. Furthermore the electron gain mass then accelerated - regarding to Einsteins Relativittstheorie. Let as have a chat. A good approximation to a black body (which is an idealization) is a cavity with a hole in it such that any light entering the hole has the opportunity to scatter off internal surfaces many many times before being absorbed. )and their energy increases, if the energy goes beyond the work function, the electron is emitted. Are Emission and Absorption the Only Ways Light Interacts With an Atom? } A cone of photons from one (of many seen objects) hits the retina. MCNPX , problem of detecting the photons in lattices. Asking for help, clarification, or responding to other answers. are called gamma rays. The vacuum is not total and it is burning in the remaining air. Specifically, it turned into heat energy. The pump is still going also - shouldn't that vapour be pretty much sucked straight out of the bowl? How can the same virtual particle both attract and repel charged particles together? What Would Happen If You Traveled At The Speed of Light? You are using an out of date browser. A pillar of gas and dust in the Eagle Nebula (M16) reveals the rich structure of the stuff that . Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Should The Anthropocene Be Added To The Geological Time Scale? An electron is an excitation in the electron quantum field. Is "different coloured socks" not correct? Glass however reflects most infrared light and absorbs ultraviolet. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. It's the additional step of "all or nothing" that gives you particles, but that's another step added on top of the issue. At a level so fundamental, physicists, as Cornell physicist David Mermin commanded (although the maxim is misattributed to Richard Feynman and sometimes Paul Dirac), shut up and calculate. Think of waves on a pond. 5 Photon number is not conserved. Gamma ray photons tend to be produced during nuclear decays, which can release a lot more energy than electronic transitions. } Why? Why do electrons in a cool gas not release photons as they are excited? color: #151515; The fact that electrons can get entangled makes more sense to me if there's a boson whizzing around inside it at the speed if light, even if it's virtual or a gague boson of sorts. They can go away just as easily. In general particles meeting their antiparticles disappear, because all quantum numbers add up to zero. Each time a photon is scattered, it can gain or lose energy, so after many scatters, it approaches the ideal curve, regardless of the emission spectrum of the material (which might have many spikes and gaps). Please downvote it instead of flagging it if you disagree with it. A photon (from Ancient Greek , (phs, phts) 'light') is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force.Photons are massless, so they always move at the speed of light in vacuum, 299 792 458 m/s (or about 186,282 mi/s). Let's look at a few of those conserved quantities: energy, impulse, electric charge. What are all the times Gandalf was either late or early?
