If the source is moving towards right, wavefront of sound waves get modifies to

A source of sound produces wave of 60 cm wavelength. This source is moving towards north with a speed one-fifth the sound speed. Find the apparent wavelength of the waves in the north and south directions.

Assertion : The apparent frequency will remain same as the frequency of source of sound if source and listener move at right angles to each other. Reason : Apparent frequency will always increase whether source is moving towards the listener or listener is moving towards the source.

A source of sound produces waves of wave length 48cm . This source is moving towards north with speed 1//4 th that of sound the apparent wave length of the waves to an observer standing south of the moving source will be

A source of sound moves towards an observer

A source of sound moves towards an observer

A source of sound produces waves of wave length 48cm . This source is moving towards north with speed V//4 where V is speed of sound. The apparent wavelength of the waves to an observer standing south of the moving source will be

An observer is moving towards the stationary source of sound, then
