A stationary sound sound 's' of frequency 334 Hz and a stationary ovserver 'O' are placed near a reflecting suface moving away from the source with velocity 2 m/s as shown in the figure. If the velocity of the sound waves is air is v= 330 m/s the apparent frequency of the echo is

Stationary sound '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/s the apparent frequency of the echo of S considering velocity of sound equal to 334 m/s is (##TRG_PHY_MCQ_XII_C07_E04_015_Q01.png" width="80%">
