Question
A stationary sound source 's' of frequency 334 Hz and a stationary observer ' O ' are placed near a reflecting surface moving away from the source with velocity 2 m/sec as shown in the figure. If the velocity of the sound waves is air is V=330 m/sec, the apparent frequency of the echo is
- 332 Hz
- 326 Hz
- 334 Hz
- 330 Hz
The correct answer is: 330 Hz
