Question

The frequency of a source of sound is $100Hertz$. How many times does it vibrate in a minute?

Answer 1

Step 1: Given data

Frequency of wave $f=100Hz$

Time $t=1minute=60seconds$

Step 2: Finding the number of vibrations in a minute

As frequency means the number of vibrations in a second, so the number of vibrations in a second is $100.$

So, the number of vibrations = $$\begin{gathered} f\times t \\ 100\times 60=6000 \end{gathered}$$

Thus, the source of sound vibrates $6000$ times in a minute.
