A person is sitting $200m$ away from a $20hertz$ sound source. What is the time interval at which successive compressions pulses from the source reach him?

Given data

Distance $d=200m$

Frequency $f=20Hz$

To determine the delay between subsequent compression pulses from the source and the man

The time period is the duration over which he receives subsequent compression pulses from the source.

As we know the frequency $f=\frac{1}{T}$

So, $T=\frac{1}{f}$

$\Rightarrow T=\frac{1}{20}\Rightarrow T=0.05s$

Hence, the time interval at which successive compressions pulses from the source reach the man is equal to $0.05seconds.$
