X-rays with energy of 300 keV undergo Compton scattering from a target. The scattered rays are deflected 37 degrees relative to the direction of the incident rays.
1. What is the Compton shift in wavelength?
2. What is the energy of the scattered x-ray?
3. What is the speed of the recoiling electron?
