A source of sound is located in a medium...

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.

Text Solution

Verified by Experts

n (apparent)=n (true) x `((v-v_("observer"))/(v+v_("source")))`, where v is the speed of sound in still air.
