The time period of the simple pendulum is 2.4 seconds.
Given the data in the question;
- Time taken to swing from leftmost point to rightmost point;
- Period of the pendulum;
Period is the time needed for a complete cycle of vibration to pass a given point.
Period of a pendulum is the of time needed for it to complete one full back-and-forth motion. It is the time required to for the pendulum to swing from leftmost point to rightmost point and back to leftmost point.
Now, if it took the pendulum to swing from leftmost point to rightmost point, it will also take the pendulum
to swing back to its original position( leftmost point )
Hence,
= time taken to swing from leftmost to rightmost + time taken to swing from rightmost point to leftmost point.
Therefore, the time period of the simple pendulum is 2.4 seconds.
