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; [tex]t = 1.2s[/tex]
- Period of the pendulum; [tex]T = \ ?[/tex]
What is Period?
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 [tex]1.2s[/tex] to swing from leftmost point to rightmost point, it will also take the pendulum [tex]1.2s[/tex] to swing back to its original position( leftmost point )
Hence,
[tex]T[/tex] = time taken to swing from leftmost to rightmost + time taken to swing from rightmost point to leftmost point.
[tex]T = 1.2s + 1.2s\\\\T = 2.4s[/tex]
Therefore, the time period of the simple pendulum is 2.4 seconds.
