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 0.591 nm, what is the energy of the scattered photon? (melectron = 9.11 × 10-31 kg, c = 3.00 × 108 m/s, h = 6.626 × 10-34 J ? s)
A. 1.05 × 1016 J
B. 2.10 × 1016 J
C. 5.71 × 1016 J
D. 3.34 × 1016 J
E. 4.21 × 1016 J
