Chapter 15, Problem 13CQ
Some bat species have auditory systems that work best over a narrow range of frequencies. To account for this, the bats adjust the sound frequencies they emit so that the returning, Doppler-shifted sound pulse is in the correct frequency range. As a bat increases its forward speed, should it increase or decrease the frequency of the emitted pulses to compensate?

Some bat species have auditory systems that work best over a narrow range of frequencies. To account for this, the bats adjust the sound frequencies they emit so that the returning, Dopplershifted sound pulse is in the correct frequency range. As a bat increases its forward speed, should it increase or decrease the frequency of the emitted pulses to compensate?
Although we can't hear them, the ultrasonic pulses are very loud. In order not to be deafened by the
sound they emit, bats can temporarily turn off their hearing. Muscles in the ear cause the bones in their
middle ear to separate slightly, so that they don't transmit vibrations to the inner ear. After an
ultrasound pulse ends, a bat can hear an echo from an object a minimum of 1 m away. Approximately
how much time after a pulse is emitted is the bat ready to hear its echo?
A. 0.5 ms
B. 1 ms
C. 3 ms
D. 6 ms
A bat can detect small objects, such as an insect, whose size is approximately equal to one wavelength of the sound the bat makes. If bats emit a chirp at a frequency of 64.0 kHz, and if the speed of sound in air is 340 m/s, what is the smallest insect a bat can detect?
