Answer:

Time period Inverse of frequency.

Thanks for Reading

Answer 2

The periodic time of the sound wave is 2.5 milliseconds.

Explanation:

It is given that, the frequency of sound waves produced from the bell of temple is 400 waves per second. Number of wave per second producing from a source is called its frequency. Here, frequency is 400 Hz.

We need to find the periodic time. We know that the relation between frequency and time period is inverse such that the time period is given by :

$T=\dfrac{1}{f}$

$T=\dfrac{1}{400}$

$T=0.0025\ s$

or

T = 2.5 ms

So, the periodic time of the sound wave is 2.5 milliseconds. Hence, this is the required solution.
