A sound source emits waves of frequency `f_(0)` and wavelength `lambda_(0)` in still air. When there is a wind blowing with speed `u` from left to right what will be wavelength of sound to the right of the source and to the left of the source.

A stationary source emits sound of frequency upsilon=1200Hz . If a wind blows at the speed of 0.1c deduce (i) the percentage change in the wavelength and (ii) the change in the frequency for a stationary observer on the wind side of the source. What happens when there is no wind, but the observer moves at speed 0.1c towards the source?

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 :

A source of sound produces waves of wavelength 60 cm when it is stationary if the speed of sound in air is 320(m)/(s) and source moves with speed 20(m)/(s) , the wavelength of sound in the forward direction will be nearest to
