X-rays of energy 2.9  104 eV are scattered by a free stationary electron through an angle of 135.
 
  What is the energy of the scattered x-rays, in electron volts? (mel = 9.11  10-31 kg, e = - 1.60  10-19 C, h = 6.626  10-34 J  s, c = 3.00  108 m/s, 1 eV = 1.60  10-19 J)

Question 2

A photon of wavelength 18.0 pm is scattered through an angle of 120 by a stationary electron. What is the wavelength of the scattered photon? (mel = 9.11  10-31 kg, h = 6.626  10-34 J  s, c = 3.00  108 m/s)
 
  A) 21.6 pm B) 22.9 pm C) 20.4 pm D) 19.2 pm E) 24.1 pm
