A source and listener are both moving towards each other with a speed v/10 where v is the speed of sound. If the frequency of the note emitted by the source is f, what will be the frequency heard by the listener?

A source emits a frequency of 1 kHz is moving toward a rest listener with a speed of 0.9 V, where V is the speed of sound wave. The frequency heard by the listener is ________ .

_____is the frequency of the sound as heard by the listener.

A source of sound and a listener are approaching each other with a speed of 40ms^(-1) The apparent frequency of a note produced by the source is 400 Hz. Then its true frequency is (velocity of sound in air = 360 ms^(-1) )

When source and listener move towards each other the apparent frequency is _________ than actual frequency.

Consider a source moving towards an listener at a speed of 0.9v. Where v is the velocity of sound. Calculate the apparent frequency if the actual frequency is 600 Hz.

__________ is the frequency of the sound as heard by the listener.

Figure shows a source of sound moving along the X-axis at a speed of 22 m s^-1 continuously emitting a sound of frequency 2.0 kHz which travels in air at a speed of 330 in s^-1 . A listener Q stands on the Y-axis at a distance of 330 m from the origin. At t = 0, the source crosses the origin P. (a) When does the sound emitted from the source at P reach the listener Q 9 (b) What will be the frequency heard by the listener at. this instant 9 (c) Where will the source be at this instant ? .

A source producing a sound of frequency 500 Hz is moving towards is listener with a velocity of 30 ms^(-1) . The speed of the sound is 330ms^(-1) . What will be the frequency heard by listener?
