Problem 36E

Why is there a Doppler effect when the source of sound is stationary and the listener is in motion? In which direction should the listener move to hear a higher frequency? A lower frequency?

Step-by-Step Solution:
Step 1 of 3

Solution 36E STEP 1: Doppler effect occurs when the source or the observer ar in motion relative to each other. It does not matter whether the source is at rest or the observer is at rest. The relative velocity of them only contributes to the Doppler effect. So, when the source of the sound is stationary but the listener is in motion, there is a change in frequency of the sound. The frequency increases if the source and listener approach each other and it decreases if they are moving away from each other. STEP 2: To hear a higher frequency, the listener should move towards the source of sound. To hear a lower frequency, the listener should move away from the source of sound.
