When both the listener and source are moving towards each other, then which of the following is true regarding frequency and wavelength of wave obserseved by the observer?

Source of sound and observer are moving towards each other, the observer will hear

When the light source is moving towards an observer,

A source of sound moves towards an observe.

A source of sound is located in a medium in which speed of sound is V and an observer is located in a medium in which speed of sound is 2V. Both the source and observer are moving directly towards each other at velocity V/5 . The source has a frequency of f_(0) . (a) Find the wavelength of wave in the medium in which the observer is located. (b) Find the frequency received by the observer.

An observer moves towards a stationary source of sound with a speed ((1)/(5)) th of the speed of sound. The wavelength and frequency of the source emitted are lamda and f, respectively. The apparent frequency and wavelength recorded by the observer are, respectively.

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
