102. A photon of frequency 4.81 x 10¹⁹ Hz scatters off
a free stationary electron. Careful measurements reveal
that the photon goes off at an angle of 125° with respect
to its original direction. (a) How much energy does the
electron gain during the collision? (b) What percent of its
original energy does the photon lose during the collision?
