(a) What is the photon's wavelength after the collision? 3.57 x 10-12 m 8.43 x 10-12 m It could be either one of the above The photon gives up some of its energy to the electron. If its energy goes down its frequency decreases and its wavelength increases. (b) Through what angle has the photon been deflected in this collision? less than 90° 90°
As wavelength increases, the energy of a photon _____ and its frequency _____. decreases; decreases The period of a wave is inversely proportional to the frequency of that wave.
