Question

A simple pendulum takes 18 seconds to complete 12 oscillations. What is

the time period of the pendulum?​

Answer 1

Number of oscillations completed by the pendulum = 12

Time taken to complete 12 oscillations = 18 seconds

Time period of the pendulum is defined as the time taken by the pendulum to complete one oscillation.

Hence,

Time period = 18/12

Time period = 1.5 seconds

Hence, the time period of the pendulum is 1.5 seconds
