Gamma rays of photon energy E are directed onto an aluminum target and are scattered in several directions by loosely bound electrons there. (Use h as the Planck's constant, c as the speed of light, m_e as the electron's mass, and E as necessary.)
(a) Determine the wavelength of the incident gamma rays?
(b) Find the wavelength of gamma rays scattered at an angle to the incident beam?
(c) Find the photon energy of the rays scattered in this direction?
