Find the velocity of source of sound, when the frequency appears to be (i) double (ii) half the original frequency to a stationary observer. Velocity of sound `= 330 ms^(-1)`.

The velocity of source of sound when the frequency appears to be double the actual frequency of stationary observer will be

What will be the velocity of source of sound if the apparent frequency received by a stationary observer is double of the original frquency ? Velocity of sound is 340 m/s.

A source of sound is moving away from an observer at rest with a velocity of 50 m s^(-1) . If the frequency of sound is 200 Hz , find the apparent frequency observed by the observer. (Take velocity of sound = 300 m s^(-1))

If the pitch of the sound of a source appears to drop by 10% to a moving person, then determine the velocity of motion of the person. Velocity of the sound =330ms^(-1) .

The source and an observer move away from each other, each with a velocity of 10m//s , with respect to ground, If the obsever find the frequency of sound coming from the source as 1950Hz, the original frequency of the source is (assume velocity of sound in air = 340ms^-1 )
