You Perform Compton Scattering Experiments with X-Rays of a Fixed

Multiple Choice

You perform Compton scattering experiments with X-rays of a fixed wavelength. In one experiment you scatter the X-rays from free electrons. In the second experiment you scatter the X-rays from protons instead. For X-rays scattered under a given angle, the wavelength change

A) will be larger for scattering from protons.
B) will be the same for both cases.
C) will be larger for scattering from electrons.
D) depends on the actual wavelength of the X-rays.
