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

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 and an observer are moving towards each other with a speed equal to v/2 where v is the speed of sound. The source is emitting sound of frequency n . The frequency heard by the observer will be

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 ________ .

When both source and listener approach each other with a velocity equal to half the velocity of sound, the change in frequency of the sound as detected by the listener is

When both source and listener approach each other with a velocity equal to half the velocity of sound, the change in frequency of the sound as detected by the listener is

When both source and listener approach each other with a velocity equal to half the velocity of sound, the change in frequency of the sound as detected by the listener is (frequency of sound = n)

A source of sound and listener are approaching each other with a speed of 40 m / s . The apparent frequency of note produced by the source is 400 cps . Then, its true frequency (in cps ) is (velocity of sound in air = 360 m / s )
