A police officer's radar gun emits radio waves at a frequency of 11.9 GHz. What is the difference in the frequencies reflected back to the radar gun by a car traveling at the 45 mph speed limit and a car travelling 1 mph faster? Assume that the cars are both headed directly away from the stationary officer. 35.54 difference between frequencies: Hz Incorrect
