Question

The frequency of a source of sound is $100\mathrm{Hz}$. How many times does it vibrate in a minute?

Answer 1

Frequency:

1. It is the number of oscillations/vibrations per second.
2. It is measured in Hertz (Hz).

Explanation:

1. If the frequency of a sound is $100\mathrm{Hz}$, it means the source of the sound completes $100$ vibrations in one second.
2. So, in one minute, the number of vibrations will be: $100\times 60=6000/\mathrm{minute}$

Hence the number of vibrations in one minute will be $6000$ times.
