An incident energetic photon is scattered by a free electron initially at rest. If the scattering angle of the scattered photon is 90∘ with respect to the incident photon propagation direction and the scattered photon energy is 0.100MeV, determine the wavelength and momentum of the scattered photon and the incident photon, respectively.
Compton effect
The incoming photons' energy must be in the range of an X-ray frequency to generate the Compton effect. The electron does not lose enough energy that reduces the wavelength of scattered photons towards the visible spectrum. As a result, with visible lights, the Compton effect is missing.
Recoil Velocity
The amount of backward thrust or force experienced by a person when he/she shoots a gun in the forward direction is called recoil velocity. This phenomenon always follows the law of conservation of linear momentum.
