A bat is flitting about in a cave, navigating via ultrasonic
bleeps. Assume that the sound emission frequency of the bat is
39,000 Hz. During one fast swoop directly toward a flat wall
surface, the bat is moving at 0.025 times the speed of sound in
air. What frequency does the bat hear reflected off the wall?
(Speed of sound in air is 343 m/s)
