Given a photon with a wavelength of 520 nm, find the energy and momentum of the photon. What equivalent mass would a particle have if all the energy of the photon were converted to mass?
*I ask that the answer be written with clear and readable handwriting or typed*
Find the momentum of a photon of ultraviolet light (130nm), green light (550nm), and infrared light (6,000nm). Also find the speed of an electron with this momentum. The mass of an electron is 9.11*10^-31.

(a) the wave shift,
(b) the angle at which the photons scatter,
(c) the angle at which the
electrons recoil, and
(d) the kinetic energy of the recoiling electrons.
