Question
A source of sound S having frequency f. Wind is blowing from source to observer O with velocity u. If speed of sound with respect to air is C, the wavelength of sound detected by O is:
Options
A.$\frac{C + u}{f}$
B.$\frac{C - u}{f}$
C.$\frac{C(C + u)}{(C - u)f}$
D.$\frac{C}{f}$
Solution
Sol. 
λ′ = λ0 + uT
= $\frac{c}{f} + \frac{u}{f}$ = $\frac{c + u}{f}$
