Answer 1

Answer:

The correct graph to show the variation of the frequency of sound with speed is option (3)

Explanation:

As we know that apparent frequency of the sound when observer is moving is given as

$n' = n(\frac{v - v_o}{v})$

above expression is valid when observer is moving away from the source

so above expression is linearly dependent on the velocity of the observer with negative slope

So the correct graph must be

option (3)
