State the doppler effect when both the source of sound and body moving in same direction...
Shukriya xD

Doppler Shift was given by Christian Johann Doppler in 1842. This apparent change in the frequency of sound as a result of relative motion between the source and the observer is the Doppler effect.
There are eight Doppler Effect Formulas for frequency depending on cases:
(i) When the source is moving towards a observer at rest.
(ii) When the source is moving away from the observer at rest.
(iii) When observer is moving towards the stationary source.
(iv) When observer moving away from a stationary source.
(v) When both Source and observer moves towards each other.
(vi) When both Source and observer move away from each other.
(Vii) When the Source is approaching the Stationary observer and observer moving away from it.
(Viii) When the Observer is approaching the Stationary source and source moving away from it.
answer:-
The Doppler effect is a phenomenon observed whenever the source of waves is moving with respect to an observer. The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for the observer and the source are approaching and an apparent downward shift in frequency when the observer and the source is receding. The Doppler effect can be observed to occur with all types of waves - most notably water waves, sound waves, and light waves.
