An observer moving towards a stationary source observes that the apparent frequency is three times the actual frequency of the source. If the velocity of sound is V, the velocity of the observer would be-

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

When the source is moving towards the stationary observer, the apparent frequency is given by

When an observer moves towards a stationary source, then the apparent pitch will

An observer moves towards a stationary source of sound of frequency n . The apparent frequency heard by him is 2 n . If the velocity of sound in air is 332 m/sec, then the velocity of the observer is

A source is moving towards a stationary observer, so that the apparent frequency increases by 50%. If velocity of sound is 330 m/s, then velocity of source is

What should be the velocity of a sound source moving towards a stationary observer so that apparent frequency is double the actual frequency (Velocity of sound is v )

If an observer moving with velocity v crosses a stationary source of frequency n, then the change in the frequency would be -

When an observer moves away from a stationary source of sound, the apparent pitch will

A source of sound is travelling towards a stationary observer. The frequency of sound heard by the observer is of three times the original frequency. The velocity of sound is v m / sec . The speed of source will be
