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.

Having read the above passage, choose the right answer to the following question (choices are higher or lower ):


Officer Ricky points a radar gun at a car. A speeding car likely has higher or lower frequency waves bouncing off of it?
