Compton Scattering: A beam of x-rays at a certain wavelength are scattered from a free electron that is at rest, and the scattered beam is observed at 45.0° from the incident beam. What is the change in the wavelength of the x-rays during this process? (melectron = 9.11 × 10-31 kg, c = 3.00 × 108 m/s, h = 6.626 × 10-34 J ? s)
A. 1.75 × 10-13 m
B. 2.76 × 10-13 m
C. 0 m
D. 3.56 × 10-13 m
E. 7.10 × 10-13 m
