Question

What is the frequency of a tuning fork that vibrates 518 times in 3.50 s?

Answer 1

Given:

The number of vibrations of the tuning fork is,

`51\text{8 times}`

in,

`t=3.50\text{ s}`

To find:

The frequency of the fork

Step-by-step explanation:

The frequency is the number of vibrations in 1 second

The frequency for the given fork is,

`\begin{gathered} \frac{The\text{ total vibrations}}{The\text{ time}} \\ =(518)/(3.50) \\ =148\text{ Hz} \end{gathered}`

Hence, the frequency is 148 Hz.
