"photons have both a matter wave and an electromagnetic wave" What does this mean? How are classical and quantum momentum related in an intuitive manner? How can you determine the polarity of unlabeled magnet? reply from potential PhD advisor? De Broglie's Matter wave equation dividing by zero. The equation you included in your question is something different: it gives the Compton wavelength of a particle, which is the wavelength of a photon that has the same electromagnetic energy as the particle's mass energy. On this site, it's best to ask questions one at a time. The non-basic waveform is then understood as a quantum superposition of states that belong to the chosen basis. My planet has a long period orbit. Why do I need to turn my crankshaft after installing a timing belt?

However, what came to my mind is the photon. 1) Yes. How do we get to know the total mass of an atmosphere? Is a software open source if its source code is published by its copyright owner but cannot be used without a commercial license? A Photon's wavelength is Color, but an Electron's wavelength is a Probability? Is the relation c=νλ valid only for Electromagnetic waves? Traditional derivation of photon momentum $p=h/\lambda$ is suspect? Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. In de Broglie hypothesis an electromagnetic wave is the de-Broglie wave for a photon moving with speed c.According to de-Broglie ,the wavelength of the photon is given by the relation: λ = h/p Why is R_t (or R_0) and not doubling time the go-to metric for measuring Covid expansion? In other words, a particle of mass $m$ has mass energy $mc^2$, and according to the formulas in my first paragraph, a photon of energy $mc^2$ will have a wavelength $\lambda = hc/mc^2 = h/mc$. The photon's matter wave is actually its electromagnetic wave. NOw use the de Broglie wavelength, Wavelength = h/MV, Plug that back in to the de Broglie eq you get the same answer. I guess yes, but how come that photons have both a matter wave and an electromagnetic wave but other particles not and that matter and electromagnetic wavelength miraculously match? Looking for a function that approximates a parabola, OOP implementation of Rock Paper Scissors game logic in Java. where the photon energy was multiplied with the electronic charge to convert the energy in Joule rather than electron Volt. Every photon is the subject to that accumulating probability. Do other planets and moons share Earth’s mineral diversity? Did genesis say the sky is made of water? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. E = mc 2, E=hλ. How does linux retain control of the CPU on a single-core machine? So the most we can say for every photon is that it is emitted in the same interval of time. The energy of a single photon of green light of a wavelength of 520 nm has an energy of 2.38 eV. 2) The de Broglie wavelength of a certain electron is. This wavelength is in the blue-violet part of the visible light spectrum. Rewriting the equation we get. De Broglie was able to mathematically determine what the wavelength of an electron should be by connecting Albert Einstein's mass-energy equivalency equation (E = mc 2) with Planck's equation (E = hf), the wave speed equation (v = λf) and momentum in a series of substitutions. Why is Soulknife's second attack not Two-Weapon Fighting? “Question closed” notifications experiment results and graduation, MAINTENANCE WARNING: Possible downtime early morning Dec 2/4/9 UTC (8:30PM…. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. Doesn't the photon have zero mass? Why can't de Broglie waves be electromagnetic in nature? To learn more, see our tips on writing great answers. Does photon has wavelength or energy corresponding to it has wavelength? What is the Difference Between emf and Potential Difference? I've edited out everything but your first question, and once you get answers to that, it will help you to formulate your second question so you can post it separately. So the wavelength relation works for photons too, you just have to use their momentum. Yes a photon has de Broglie wavelength.In 1924,Louis de Broglie proposed that a particle must also act like wave,in silmilar way,wave behave like particles. Your email address will not be published. The equation you should be using is. (Some advanced details are omitted.). What's the current state of LaTeX3 (2020)? site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. Hi user24298, and welcome to Physics Stack Exchange! $$\frac{h}{mc} = \lambda$$ Save my name, email, and website in this browser for the next time I comment. It only takes a minute to sign up. 4) The question is based on the wrong assumption, see the answer to the question 2. How the electromagnetic wave is built up is written up here : This is unclear; at the moment, I don't think it answers the question well. What you have there isn't actually de Broglie's equation for wavelength. 2) Photon emission is not such a kind of process when you get some particles emitted in some interval of time, and you can assume some emission moment within that interval to every particular particle. In Monopoly, if your Community Chest card reads "Go back to ...." , do you move forward or backward? because photons have momentum associated with them when they are in motion even though they don't have a rest mass. do electron tend to go to regions of high potential or low potential? m is the mass. The kinetic energy of an electron is related to its momentum by: T = p 2 /2m. 3) The same way as you may interpret some particular waveform in different bases, like a function of time or a set of sinewave weights, you can interpret photons in different bases. What if the P-Value is less than 0.05, but the test statistic is also less than the critical value? How to consider rude(?) I edited your post to use mathjax only to show you, how simple is it. Use MathJax to format equations. The speed of the wave = wavelength x frequency, say the frequency is 6.0 x 10^14 Hz calculate the wavelength. No, it is a quantum process. Solve for parameters so that a relation is always satisfied. As is obvious, it relates the wavelength to the mass of an object. substituting equation (2) in equation (1) we get. How to derive derive De-Broglie's wavelength equation? Why does Slowswift find this remark ironic? Yes a photon has de Broglie wavelength.In 1924,Louis de Broglie proposed that a particle must also act like wave,in silmilar way,wave behave like particles. You deleted your 4 questions, leaving just one, but I hope my answers would still help you. In "Star Trek" (2009), why does one of the Vulcan science ministers state that Spock's application to Starfleet was logical but "unnecessary"? 2: The de Broglie wavelength of the electron is 0.26 nm. Difference between DeBroglie wavelength and wavelength of radiation, De Broglie wavelength, frequency and velocity - interpretation. = 442 Nano meter. Are there temporal limits to data requirements for a GDPR SAR? Therefore, won't the wavelength be infinity and the particle nature of the particle non existent? Is the de Broglie wavelength of a photon equal to the EM wavelength of the radiation? MathJax reference. NOw use the de Broglie wavelength, Wavelength = h/MV use E=hv to get the energy than, Use E=MC^2 to get the mass For what modules is the endomorphism ring a division ring? How to find Vernier caliper least count formula? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. What is the best way to remove 100% of a software that is not yet installed? What kind of overshoes can I use with a large touring SPD cycling shoe such as the Giro Rumble VR? λ = 442 nm The de Broglie wavelength of the photon is 442 nm. Energy of a photon calculator The energy of a single photon is a small number because the Planck constant is ridiculously tiny. $c=\lambda\nu$, so $\lambda=\frac{c}{\nu}$ and $\Delta E=\frac{hc}{\lambda}$. Should we leave technical astronomy questions to Astronomy SE? As a side effect you can derive that $\lambda = hc/E$ for photons. What does commonwealth mean in US English? hλ=mc 2. m =hλ/c 2 ————-(2) h= Planck’s constant(6.62607015×10 −34 Js) λ = wavelength of light. P.S. The system's intermediate states are not "some particles are emitted, and some are not emitted yet", but "system has some intemediate probability to be in the initial state, and some probability to be in the final state".
