Question

c) Suppose you are pulled over for running a red light. You try to trick the officer who pulled you over and say that due to the Doppler shift, you didn't even see a light. However, the officer knows physics and decides to give you a ticket based on the speed needed to shift red light to ultraviolet light if the light was stationary. The officer decides to give a ticket which is $10 for every mile per hour you were travelling. If the frequency of red light is 421 x 10¹² Hz and the frequency of ultraviolet light is 881 x 10¹² Hz, what would the price of your ticket be in billions of dollars?
