State the expression for apparent frequency when listener is stationary and source is moving towards the listener.

उत्तर
Let, n = actual frequency of the source.
n0 = apparent frequency of the source.
v = velocity of sound in air.
vs = velocity of the source.
v1 = velocity of the listener.
If source is moving towards observer then apparent frequency is given by,
n = `"n"_0("v"/("v" - "v"_"s"))`, i.e., apparent frequency increases.

In discussing Doppler effect, we use the word "apparent frequency". Does it mean that the frequency of the sound is still that of the source and it is some physiological phenomenon in the listener's ear that gives rise to Doppler effect? Think for the observer approaching the source and for the source approaching the observer.
Answer briefly.
What is Doppler effect?
