Question

A person 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?

Answer 1

Step 1: Given that:

The frequency(f) of the tone = $500Hz$

Distance of the sound source from the person = $450m$

Step 2: Concept and formula used:

The time interval between successive compressions is equal to the time period of the wave. And this time period is the reciprocal of the frequency of the wave.

That is,

$Timeperiod\left(T\right)=\frac{1}{Frequency\left(f\right)}$

Step 3: Calculation of time interval between successive compressions from the source:

$T=\frac{1}{500Hz}$

$T=0.002sec$

Thus,

The time interval between successive compressions from the source is $0.002sec$ .
