Chapter 16, Problem 71P
The Doppler effect using ultrasonic waves of frequency 2.25 × 106 Hz is used to monitor the heartbeat of a fetus. A (maximum) beat frequency of 260 Hz is observed. Assuming that the speed of sound in tissue is 1.54 × 103 m/s, calculate the maximum velocity of the surface of the heating heart.
