Echolocation, also called biosonar; is the biological sonar used by several kinds of animals. Echolocating animals emit calls out to the environment and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects. Echolocation is used for navigation and for foraging in various environments. Echolocating animals include some mammals and a few birds; most notably microchiropteran bats and odontocetes (toothed whales and dolphins). In this ponderable, a stationary bat emits a steady sound at 20,0 KHz frequency. The bat detects the echo from a moving insect at a frequency that is 200 Hz higher than it emits with a delay time of 0.1s. How fast is the insect moving relative to the bat, and is the insect flying away or toward the bat? How far away is the insect?
