Question

A sound wave produces 60 compressions and 60 rarefactions in .6 sec then the frequency of sound wave

Answer 1

The no. of vibration per second is called frequency
v=1/T
v=1/6
v=.166hz

Answer 2

The frequency of the sound wave is 1.67 Hz.

Explanation:

It is given that, a sound wave produces 60 compression and 60 rarefaction in 0.6 seconds. We need to find the frequency of the sound wave. If f is the frequency of the sound wave. It is given by :

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

$f=\dfrac{1}{0.6\ s}$

f = 1.67 Hz

So, the frequency of the sound wave is 1.67 Hz. Hence, this is the required solution.
