Question

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

Answer 1

Step 1: Given data.

Frequency, $f=500Hz$

Distance, $d=450m$

Time period, $T=?$

Step 2: Calculate the time period.

Time period of the wave is the time interval between successive compressions or rarefactions from the source.

It is calculated below:

$\begin{array}{rcl}T& =& \frac{1}{f}\\ & \Rightarrow & T=\frac{1}{500Hz}\\ & \Rightarrow & T=0.002s\end{array}$

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