In the case of sound waves, wind is blowing from source to receiver with speed 
. Both source and receiver are stationary. If 
is the original wavelength with no wind and V is speed of sound in air then wavelength as received by the receiver is given by
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
There is no relative motion between source and observer so frequency remain constant
n = 
when wind start blowing in the direction of wave motion then velocity of sound = V + u w
so apparent wave length λ' = 
= 
λ 0
