Question

Hello all❤

Class 11th : physics ✌✌

State the doppler effect when both the source of sound and body moving in same direction...
(state formula)


Shukriya xD

Answer 1

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 2

Doppler effect

The Doppler effect is the change in the observed frequency of a wave when the source or the detector moves relative to the transmitting medium.

The Doppler effect occurs when a source of waves and/or observer move relative to each other, resulting in the observer measuring a different frequency of the waves than the frequency that the source is emitting. The medium that the waves are travelling through, the transmitting medium, is also stationary in the cases we will study.
