A 700 keV gamma ray is incident on an electron at rest. If the scattered photon has a scattering angle of 115° with respect to the direction of the incident photon, determine the following. (a) Energy (in keV) of the scattered photon keV (b) Kinetic energy (in keV) of the scattered electron keV (c) Recoil angle (in degrees) of the scattered electron
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.
