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?

Given,

Frequency (ν) = 500 Hz

The time interval between successive compressions from the source is equal to the time period.

We know,

time period (T) = $\dfrac{1}{\text{ν}}$

Substituting we get,

T = $\dfrac{1}{500}$ = 0.002 s

Hence, time interval between successive compressions from the source = 0.002 s.
