what is doppler effect
Answers
Answer:
The Doppler effect (or the Doppler shift) is the change in frequency of a wave in relation to an observer who is moving relative to the wave source. ... Compared to the emitted frequency, the received frequency is higher during the approach, identical at the instant of passing by, and lower during the recession.
Answer:-
It is the appearant change in the frequency or in the pitch because of the relative motion along the observer's line of sight and the source is known as Doppler Effect.
* It is valid for for both sound and light.
* In the light it depends on the distance between the source and the observer.
* While in sound it depends on distance between the observer and the source.
Explaination:-
In order to apply Doppler effect first we need two assumptions those assumptions are as follows:-
(i) The observer's velocity and source velocity must be less than to the velocity of the Sound.
(ii) The velocity of source observer and also the medium should be along the joining position of the source and the observer.
