In Example 16.18 (Section 16.8), suppose the police car is moving away from the warehouse at 20 m/s. What frequency does the driver of the police car hear reflected from the warehouse?
ANSWER:Solution 44E Assume the speed of sound in air to be v = 343 m/s. For the source Velocity v = 20 m/s s Frequency f =s300 Hz Using a doppler equation for an approaching sound source f = v 0* f0/v0 v s f = (v v s/v * f 0 0 0 Reflected frequency = apparent frequency f = v 0* f0/v0 v s f = (v + v s/v f 0 0 * 0 In this s
