What is dopplers effect derive an expression for the apparent frequency of sound when source is at rest and observer is in motion long answer in 5 marks?

Answer 1

Answer:

Answer:Derive an expression for the apparent frequency received by observer when alone source is in motion.

(Assume media to be at rest). Doppler's effect is the change in the pitch when there is a relative motion between source and observer. Let a source which is at rest be emitting waves of frequency f and wavelength (lemda)
