Compton Scattering: a Photon of Initial Wavelength 0

question 8

Essay

Compton scattering: A photon of initial wavelength 0.651 nm, after being scattered from a free electron at rest, moves off at an angle of 120° with respect to its incident direction. (m_el = 9.11 × 10^-31 kg, h = 6.626 × 10^-34 J ∙ s, c = 3.00 × 10⁸ m/s)
(a) What is the wavelength of the scattered photon?
(b) What is the energy of the scattered photon?
