Question

Two sources of sound $S_1$ and $S_2$ produce sound waves of same frequency 660 Hz . A listener is moving from source $S_1$ towards $S_2$ with a constant speed $u \mathrm{~m} / \mathrm{s}$ and he hears 10 beats $/ \mathrm{s}$. The velocity of sound is $330 \mathrm{~m} / \mathrm{s}$. Then, u equals:

Select the correct option:

A

10.0 m/s

B

5.5 m/s

C

2.5 m/s

D

15.0 m/s

✓ Correct! Well done.
