Consider again the insect in Problem 58. If the insect moves the 10-cm distance in 0.50 s, what is the magnitude of the Doppler shift in the bat’s reflected sound wave? Assume the insect is moving directly away from the bat.

Data From Problem 58

A bat is pursuing an insect and using echolocation of 60-kHz sound waves to track the insect. The insect is initially 30 cm from the bat, but then moves to a distance of 40 cm as it tries to escape. What is the difference in the two echo times the bat measures?
