The frequency of a source of sound is $100\ Hz$. How many times does it vibrate in a minute?
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 $=100\times 60$ [$\because 1\ minute=60\ seconds$ ]
$=6000\ times$
