A police car on the side of the road (at rest) uses a radar gun
to catch speeders as they approach it. The frequency the radar gun
emits is 8 x 109 Hz and the speed limit is 65 mi/hr.
a)What is the frequency of the radio wave that the car "sees"?
Since they cant really see:)
b)What is the frequency of the reflected radio wave that is picked
up by the receiver inside the radar gun?
