A bat locates insects by emitting ultrasonic "chirps" and then listening for echoes from the bugs. Suppose a bat chirp has a frequency of 25 kHz. In what direction would the bat have to fly for you to just barely be able to hear the chirp at 20 kHz? ▸ away from you toward you in another direction How fast would the bat have to fly for you to just barely be able to hear the chirp at 20kHz?
