Question

The bob of a pendulum takes 0.50 seconds to go from one extreme position to the mean position.

Calculate the time period of the pendulum.​

Answer 1

If the time taken by one pendulum to reach its mean position from the extreme position is 0.25 seconds then a pendulum will move to two extreme positions from one mean position only. That will means that the total time period = 2 * 0.25 = 0.50 seconds.
