Question: The cop shot the radar gun at the super slow car, which _____ the waves. 
 Answer: decreased

Ex Output:

A: As the car approaches the radar gun, the reflected microwaves get bunched up in front of the car. Therefore, the waves the receiver detects have a higher frequency than they would if they were being reflected from a stationary object. The faster the car is moving, the greater the increase in the frequency of the waves.
