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?

What is the physical change occurs when the source of sound is stationary but the observer moves?

A source of frequency 1 kHz is moving towards a stationary observer with velocity of 0.9 times that of sound. What is the frequency heard by the observer ?

Show that when the speed of the source and the observer are small compared to the speed of sound in the medium, the change in frequency becomes independent of the fact whether the source is moving or the observer.
