7. 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 the bat emits a chirp at frequency 125 kHz, and
the speed of sound in air is 343 m/s. What is the wavelength of the sound emitted by the bat?
8. A stone is dropped into a well. A bang, from hitting the bottom of the well, is heard 15 seconds
later. How deep is the well? Assume that the speed of sound in air is 343 m/s.
