An X-ray beam with λ=8.45 x10-11 m hits a metal target and X-rays are observed to be scatteredat an angle of 65.0 degrees with respect to the incident beam. Consider the conduction electrons in the target to be so loosely bound that they can be treated as free electrons at rest.

a) What is the wavelength observed for the scattered light? (pm)

b) What is the kinetic energy given to the recoiling electron ? (eV)

c) Is the electron relativistic? Justify your Yes or No answer quantitatively based on its kinetic energy.
