Consider compton scaterring of a photon by a moving aelectron.Before the collision the photon has a wavelengthand is moving in a +ve x direction,and the electron is moving in the -ve x direction with the total energy E (= mc^2).The photon and the electorn had the head on collision.After the collision both are moving in the -ve x direction ; I mean that photon has been scaterred by 180 degrees.Derive an expression for the new wave length of the scaterred photon, if E New Wave length = hc/E. (1+ m 2 c 4 .old wave length /4hcE)
