A stationary sound source S of frequency 334 Hz and a stationary observer O are placed near reflecting surface moving away from the source with velocity 2m/s as shown in figure. Velocity of sound waves in air v = 330 m/s. The apparent frequency of echo is –
Text Solution
Verified by ExpertsThe correct answer is:
D
F echo = f ac 
= 334 
= 334 × 
= 330 Hz
