Police radar guns measure the speed of moving vehicles by transmitting electromagnetic waves at a vehicle and detecting a Doppler shift in the reflected wave. Suppose a police radar transmits at a frequency of 22.0 GHz and receives a wave reflected from a car moving toward the radar at 69.0 mph. Find the frequency shift Affofs (in Hz) between the observed (received) and source (transmitted) frequencies. HINT -0.019507 ҳ Hz Need Help? Submit Answer Read It ♡
