1. X-ray photons of wavelength 0.02480 nm are incident on a target and the Compton- scattered photons are observed at 90.0 •. (a) What is the wavelength (in nm) of the scattered photons? (b) What is the momentum of the incident photons? Of the scattered photons? (c) What is the kinetic energy of the scattered electrons? (d) What is the momentum (magnitude and direction) of the scattered electrons?
