Question

The time period of a definite sound wave measured in a medium is 5 seconds.Calculate the frequency of the wave?

Answer 1

Frequency of sound wave will be 0.2 Hz

Explanation:

We have given time period of a definite sound wave is measured as 5 sec

We have to find the frequency f

Frequency is number of cycles per second it means frequency will be inverse of time period

So frequency $f=\frac{1}{T}=\frac{1}{5}=0.2Hz$

So frequency of sound wave will be equal to 0.2 Hz
