A police officer's radar gun emits radio waves at a frequency of 10.5 GHz. What is the difference in the frequencies (Hz) reflected back to the radar gun by a car traveling at the 55 mph speed limit and a car travelling 1 mph faster? Assume that the cars are both headed directly away from the stationary officer.
