X-rays strike a stationary target and undergo Compton scattering. If the energies of the incident and scattered X-ray are 485 keV and 300 keV respectively, determine the scattering angle (in degrees). 0 2. [-/1 Points] DETAILS OSCOLPHYS2016 29.4.WA.024.TUTORIAL. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A photon moving in the +x-direction, scatters off a free stationary electron. The wavelength of the incident photon is 0.0310 nm. After the collision, the electron moves at an angle a below the +x-axis, while the photon moves at an angle 0 = 77.3 above the +x-axis.
