Question

A photon with wavelength 0.1365 nm scatters from an electron that is initially at rest.

What must be the angle between the direction of propagation of the incident and scattered photons if the speed of the electron immediately after the collision is 9.00×10⁶ m/s ?

Answer 1

let after scattering wavelength of photon be a then from conservation of energy en este sens de la meves s he the Limited 2hc 9,61013 !

Alright Dude, If this worked for you... Don't forget to give THUMBS UP ( that will work for me)
