Compton Scattering: A certain photon, after being scattered from a free electron that was at rest, moves at an angle of 120° with respect to the incident direction. If the wavelength of the incident photon is 0.6110 nm, what is the kinetic energy of the recoiling electron? (melectron = 9.11 × 10-31 kg, c = 3.00 × 108 m/s, h = 6.626 × 10-34 J ? s)
A. 1.5 × 10-18 J B. 1.9 × 10-18 J C. 3.1 × 10-18 J D. 4.3 × 10-18 J E. 5.2 × 10-18 J
