Question

A pendulum makes 60 complete oscillations in 20 seconds. What is the period of oscillation? What is the frequency of the pendulum? Use appropriate units

Answer 1

No. if oscillation = 60

Time period = 20 second

So, frequency of pendulum =

$\frac{60}{20 \: sec}$

3 Hz (hertz)

Hope this helps. Please mark as the brainliest answer.

Answer 2

Pendulum Make Oscillation=60

In =20 seconds.

In 1 second=60/20

=3

Oscillation Per/Second=3

We know Oscillation per Second is called Oscillation.

SI unit of Frequency=Hertz

So Frequency=3 Hertz

Time Period of Oscillation

$\frac{1}{number \: of \: oscillation \: per \: second}$

$\frac{1}{3} \\ \\ = 0.33$

Period Of Oscillation=0.33 seconds

Means in every 0.33 seconds it Done 1 oscillation
