In the case of sound waves, wind a blowing from source to reciver with speed `U_(W)`. Both source and receiver are stationary.If `lambda_(0)` is the original wavelength with no wind and `V` is speed of sound in air then wavelength as received is given by :
A. `lambda_(0)`
B. `((V + U_(W))/(V))lambda_(0)`
C. `((V - U_(W))/(V))lambda_(0)`
D. `((V)/(V + V_(W)))lambda_(0)`
