A source and a detector moveaway fro each other, each with a speed of 10 ms^-1 with respect to the grond with no wind. If the detector detects a frequency 1950 Hz of the sound coming from thesorce, what is the original frequency of the source? Speed of sound in air =340 ms^-1 .

A source and an observer approach each other with same velocity 50 m/s. If the apparent frequency is 434 Hz, then the real frequency is (Given velocity of sound = 332 m/s)

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 )

A source emits a frequency of "290Hz" .An observer is moving away from the source with a velocity "20ms^(-1)" and the source is moving away from the observer with a velocity "10ms^(-1)" .The wind is blowing in a direction from the observer to the source with a velocity "5ms^(-1)" .The apparent frequency heard by the observer is (Velocity of sound in air "=343ms^(-1)" )

On the same path, the source and observer are moving such a way that the distance between these two inicreases with the time. The speeds of source and observer are same and equal to 10ms^(-1) with respect to the ground while no wind in blowing. The apparent frequency received by observer is 1950 Hz then the original frequency must be (the speed of sound in present medium is 340 m//s

A source of sound is travelling towards a stationary observer. The frequency of sound heard by the observer is 25 % more than the actual frequency. If the speed of sound is v , that of the source is

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))

A source of sound, producing a sinusoidal wave, is moving uniformly towards an observer at a velocity of 20 m/s. The observer is moving away from the source at a constant velocity of 10 m / s. Frequency of the source is 200 Hz and speed of sound in air is of 340 m/s. (a) How many times, in an interval of 10 second, the eardrums of the observer will sense maximum change in pressure? (b) What will be apparent wavelength of sound for the observer?

A source is moving towards an observer with a speed of 20 m / s and having frequency of 240 Hz . The observer is now moving towards the source with a speed of 20 m / s . Apparent frequency heard by observer, if velocity of sound is 340 m / s , is

A source of sound S is moving with a velocity of 50m//s towards a stationary observer. The observer measures the frequency of the source as 1000 Hz. What will be the apparent frequency of the source as 1000 Hz. What will be the apparent frequency of the source when it is moving away from the observer after crossing him? The velocity of the sound in the medium is 350m//s
