Compton scattering : how we know light has momentum

Compton scattering is the effect of photons of rays scattering electrons, and provided evidence for the. particle nature of light. This video covers an explanation and the mathematical relationship that Arthur Compton derived by assuming a quantum nature and conservations laws.

Very nice explanation, couldn't understood what Compton did from his paper and other videous. Big thanks!

[neelansatchi]

I don't know if there is anyone better at explaining physics like you sir.

Really excellent tutorial, thanks! It's remarkable how classical physics (momentum, conservation laws) is embraced by the quantum machinists to explain this phenomenon but is set aside when it is inconvenient e.g. electrons emitting EM radiation.

This video was of great help for my physics students, but unfortunately you got the last graph wrong, which caused a lot of confusion. The maximum has to be at pi and it is not the compton wavelength (which is at pi/2).

Besides that, it's the most compact explanation of compton scattering i ever saw, so: Great work! Thanks!

1:49 sir crystals here is referring to crystal like diamond or crystals like the ionic crystal lattice structure ? thanks u a lot for your work by the way . It really helps a lot !

Great stuff ... but the last graph should look differently as delta lambda is max at pi rad. Your graph has a maximum at pi/2, which is the Compton wavelength!

Paul's "high school" physics is superior to anything else I've seen for the layman on Compton scattering. For me at least, after reading about many milestone experiments, Compton's experiment involves exceptionally dense theory and exceptional results. Any small error at the end pales in comparison to the light shed.

Hi..so I have some questions
1. What is the maximum angle of recoil for the electron?
2. In my text book it is said unmodified line occures due to bound electrons and the whole atom recoils...but photoelectric effect is also due to bound electron. What is the difference

Thanks for the video..have a good day🤗

Great video for students in Grade 12. Very clear and easily understood. Thank you!

[HeliosNation]

Thank u a lot very appreciated. The best one ever explaining physics !! Thanks a lot !

Hi, Can you help me answer this question I have about Inverse Compton Scattering?

[divyanshugreninja]

Sir, I have a question, Compton wanted to find out the change in the wavelength of the photon then why did he involved the mass of the electron in his equations ?? Was that due to the law of conservation of energy?? Please explain me sir

[nosferatu]

At pi its 2 times the compton wavelength

Awesome 👍 explanation. Can you like me sir
