Problem 48E

Unless indicated otherwise, assume the speed of sound in air to be v = 344 m/s. Moving Source vs. Moving Listener. (a) A sound source producing 1.00-kHz waves moves toward a stationary listener at one-half the speed of sound. What frequency will the listener hear? (b) Suppose instead that the source is stationary and the listener moves toward the source at one-half the speed of sound. What frequency does the listener hear? How does your answer compare to that in part (a)? Explain on physical grounds why the two answers differ.

Step-by-Step Solution:
Step 1 of 3

Solution 48E Frequency of the source f = 1.00 kHz (a) Speed of the source is = v/2 The apparent frequency heard by the listener is f 1 = v f (vv/2) f = 2f 1 f 1 = 2 × 1.00 kHz f 1 = 2.00 kHz (b) Now, the listener moves toward the source at = v/2 The apparent frequency heard by the listener is f 2 = vvv/2f f 2 = 3f/2 f = 1.5 × 1.00 kHz 2 f = 1.50 kHz 2 The reason for the difference is that in the first case, the source is moving. But the second case, the source is stationary even though in both cases, both the listener and the source have the same speed.
