In a Compton scattering experiment, an X-ray photon that has a wavelength of 0.130 nm is incident on a free, initially stationary electron. The scattered X-ray photon, which has a wavelength of 0.135 nm, travels back the way the incident photon came. Before Path of incident photon Free electron 2 = 0.130 nm After Path of scattered photon Free electron 2 =0.135 nm 193. The magnitude of the final momentum of the electron is A. 1.33 x 10-22 kg.m/s B. 1.00 x 10-25 kg.m/s C. 5.10 x 10-24 kg.m/s D. 4.91 x 10-24 kg.m/s
