Question

A simple pendulum completes 60 vibrations in30 seconds.Find the frequency and time period of the vibration

Answer 1

Here is your answer

Frequency= No. of oscillations in 1 second

It is given that

No. of oscillation in 30 sec = 60

Then, No. of oscillation in 1 sec = 60/30

= 2 /s = 2 hz(as 1/s = 1 hz)

Time period = Time taken to complete one oscillation

= 1/frequency = 1/2 = .5 sec
