A person is listening to a tone of 500 Hz sitting at a distance of 450 m from the source of the sound. What is the time interval between successive compressions from the source?

The time interval between successive compressions from the source is equal to the time period and time period is reciprocal of the frequency.

\(\therefore T= \frac{1}{F} \)

\(\Rightarrow T= \frac{1}{500} \)

\(\therefore T = 0.002 s \) .
