Question

A particle is connected to a horizontal spring and set into vibration. If it makes 50 oscillations during 2 seconds, then its frequency is:

Answer 1

Given data:

The number of oscillations of the particle in 2 seconds is 50.

Solution:

The frequency is defined as the number of oscillations of the particle in one second.

Thus, the frequency of the oscillation of particle is,

$f=\frac{n}{t}$

where n is the number of oscillations, and t is the time,

Substituting the known values,

$\begin{gathered} f=\frac{50}{2} \\ f=25\text{ Hz} \end{gathered}$

Thus, the frequency of oscillation is 25 hertz.
