Doppler's effect

Question

A source of sound of frequency n is moving towards a stationary observer with a speed S. If the speed of sound in air is V and the frequency heard by the observer is n₁, the value of $n_{1} / n$ is

Easy

A

$(V + S) / V$
B

$V / (V + S)$
C

$(V - S) / V$
D

$V / (V - S)$

Solution

By using $n^{'} = n \frac{v}{v - v_{S}} \Rightarrow \frac{n_{1}}{n} = (\frac{V}{V - S})$
