Compton Effect reveals Photon nature of light (Derivation)

Imagine a photon bouncing off an electron. This is the Compton Effect. When a photon collides with an electron and exchanges momentum and energy, as they get scattered in different directions, we get Compton Effect.

The Compton effect is a phenomenon in which a photon (a particle of light) collides with an electron, causing the photon to lose some of its energy and change its direction. This effect is a crucial piece of evidence for the particle-like behavior of light, which is a fundamental concept in quantum mechanics. The Compton effect is also used in X-ray technology to image the inside of objects and has important applications in fields such as medicine and materials science.
The Compton Effect provides irrefutable evidence regarding the Photon picture of light. Light consists of particles called photons that can undergo in-elastic collision with other particles like electrons.
In this video I derive the Compton Shift Equation, as well as fractional loss of Energy of Incident photon.

[@luisalfredoixquiacmendez8494]

Professor!, in an interaction of a photon with a free stationary electron, is it possible to predict the scattering angle of the photon? Or to predict a probability distribution of this scattering angle? Predict it only in terms of the initial state of the system.

[@conceptualphysics1705]

Aslmualikm.. Sir plz tell me the Anwer of this question.. Q. Why we have high intensity peak of scattered Photon compared to original x rays Photon... I mean peak to peak...

[@gok_dogan]

Because of Heisenberg uncertainty principle we couldn't dedect position and momentum of an electron simultaneously. Thus we can not predict before collision of electron and photon.

[@himanshusharma-lj4gt]

sir you way of explaining is really awesome

[@unbredsundew4213]

Thank you for your awesome teaching!

[@thirunavukarasua4151]

The energy of the photon hf is observed completely by the electron in photoelectric effect. But in Compton effect the photon transfers only part of its energy to electron and scatters with less energy. Doesn't seem contradictory? Could you please explain the physics behind this..

[@Pavan_Gaonkar]

I think the reason is the if you want to take out the electron from the atom you need to provide a certain amount of energy .. otherwise it won't get out of the atom.. but in collision there is no such restriction..

[@Abhi-mu2cy]

​@@Pavan_Gaonkar I too think the same infact in photoelectric effect photon's energy must cross certain threshold energy but in Crompton scattering there is no such conditions

[@Abhi-mu2cy]

But the question arises that for high energy photon Crompton scattering is dominant so which one happens photoelectric effect or Crompton scattering? (The photon energy is above the threshold energy)

[@maazsarfaraz2269]

If you remember in P.E.E we have a work function of emiter and to emitt electrons energy of incident photon should be greater ,but here there is no such condition , and we also have x and gamma rays that cause comptons effect ,it s that only x and gamma rays cause comptons effect

[@honestlybruhidk]

Sir literally thank you just thank you

[@GlinnHansen]

Terrific lecturer. Explains topic very well, clearly and concise. I do have a question. How can a scattered electron obtain a velocity of the speed of light by colliding with a single photon?

[@rajeshvaghela12]

i think electron would not have speed of light, or if it does then it must be moving around nucleus at that speed, photon just give it other direction while colliding. in fact in current, electron just move by micro or nano meter, it is wave which travel speed of C

Thanks a lot sir ..

[@PrivateSi]

Hi there, I just wondered why many people seem to imply it's the 'hits per second' that counts as 'higher energy' instead of a single wave / photon approach which would be the acceleration curve of the wave on the electron. Frequency is not a good term to use in conjunction with the photoelectric effect to me as it locks in the idea of multiple waves needed to free an electron, instead of one short wave = very fast electron acceleration.. I know it's a convention and makes sense from a wave beam / oscillating system point of view but not photonically. More photon hits should produce more electron photons if the incoming photons are above the atom's energy threshold.

This is a nice mathematical shortcut, but unfortunately for Compton, we know that electrons can not absorb fractions of photons. The math might work out right, but the physics here can not be correct.

[@FortheLoveofPhysics]

Electron absorbed portion of the photon energy, like a ball absorbs portion of energy upon collision

[@Naomi_Boyd]

@@FortheLoveofPhysics Yes, that was Compton's theory, but as I said, we know that can not happen. Also, you use a stationary electron for an example, and we know that can not happen either. The billiard analogy is like Bohr's planetary model of the atom. It works as a mathematical tool, but it is not an accurate model of reality.
