When source of sound moves towards a stationary observer, the wavelength of sound received by him

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

At what speed should a source of sound move so that observer finds the apparent frequency equal to half of the original frequency ?

The frequency of a source of sound as measured by an observer when the source is moving towards him with a speed of 30 m/s is 720 Hz. The apparent frequency when the source is moving away after crossing the observer is x xx 10^2 Hz what is the value of x. ......... (velocity of sound is 330 m/s)

In Dopplers effect, when a source moves towards a stationary observer, the apparent increase in frequency is due to

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

(A) : When a source moves towards a stationary observer, the speed of source relative to the observer remains unchanged. (R): The apparent change in frequency is due to change in the wavelength brought by the motion of the source.

A source of sound and an observer are approaching each other with the same speed, which is equal to (1/10) times the speed of sound. The apparent relative change in frequency of source is

A source of sound emitting a note of frequency 200 Hz moves towards an observer with a velocity v equal to the velocity of sound. If the observer also moves away from the source with the same velocity v, the apparent frequency heard by the observer is

(a) Does the change in frequency due to Doppler effect depend on the distance between source (b)Does the change in frequency due to Doppler effect on the fact that source is moving towards the observer or observer is moving towards the source ?
