With what velocity an observer sould move relative to a stationary source so that he hears a sound of double the frequency of souce?

A

half the speed of sound

B

equal to the speed of sound

C

double the speed of sound

D

thrice the speed of sound

Text Solution

Verified by Experts

The correct Answer is:
B
`n' = ((V + V_(0))/(V)) n :. 2 = (V + V_(0))/(V)`
`:. 2V = V + V_(0)`
`:. V_(0) = V =` Velocity of sound
