In a Compton scattering experiment, an x-ray photon scatters through an angle of 20.2° from a free electron that is initially at rest. The electron recoils with a speed of 2,440 km/s. (a) Calculate the wavelength of the incident photon. nm (b) Calculate the angle through which the electron scatters.
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.
