The frequency of a source of sound is \(600\) \(Hz\). Calculate the number of times it vibrates in a minute?

The formula to find time period is

$Time period = \frac{1}{wavelength}$
$Number of times = frequency \times time period$

By applying the known values in the formula, we get

\(number of vibration\) \(=\)

The unit is .
