Given: The frequency of a source of sound is $100\ Hz$.

To do: To find the number of vibrations in a minute.

Solution:

Given that,

Frequency $=100\ Hz$

It is known that the number of vibrations in a second is called frequency.

Therefore, the source of sound vibrates $100$ times in one second if the frequency of a source of sound is $100\ Hz$.

Therefore, number of vibrations in 1 minute $=100\times 60$     [$\because 1\ minute=60\ seconds$ ]

$=6000\ times$
