An incident x-ray photon with a wavelength equal to 0.0900 nm is scattered back in the opposite direction by a free electron that is initially at rest. (a) What is the modulus of the linear momentum of the scattered photon? (b) What is the kinetic energy of the electron after the photon is scattered?
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.
