when a source is going away from a stationary observer with the velocity equal to that of sound in air , then the frequency heard by observer is `n` times the original frequency . The value of `n` is

A

same

B

half

C

double

D

one third

Text Solution

Verified by Experts

The correct Answer is:
B
`n' = ((V)/(V + V_(s))) n = ((V)/(2V)) n = (n)/(2)`
