Question
A whistle producing sound waves of frequencies 9500 Hz and above is approaching a stationary person with speed v ms-1. The velocity of sound in air is 300 ms-1. If the person can hear frequencies upto a maximum of 10,000 Hz, the maximum value of v upto which he can hear the whistle is
Options
A.30 ms-1
B.15 √2 ms-1
C.15 /√2 ms-1
D.15 ms-1
