A bat moves with speed vp toward an obstacle and sends out ultrasonic sound waves at frequency f and receives them returned from the obstacle at frequency 3 (returning echo). If the returning echo frequency is 20% above the original sound frequency (f3 = 1.2 f), find the bat speed. V ultrasound = 330 m/s.

Answer rating: 100% (QA)

To find the bat speed we can use the formula for the Doppler effect f... View the full answer
