File talk:Doppler effect diagrammatic.png

Doppler Effect, the sound feel higher when it comes to you, but when it pass you the sound goes away (A good example is police cars) It sends the waves infront of the object(In this case a car).

The sender Vr f' = f - \frac{v_r}{\lambda} = f - \frac{v_r f}{v} = f \left(1 - \frac {v_r}{v} \right)

When the Object gets "The Swag" And the sender gets "Yolo" it'll became a wave full with chillipill (Which is an Error, When a elefant slowly poop in the forest) To stop the Error you have to say- Habila
