Understanding Pendulum Motion: Determining Period from Position-Time Graph

I'm sorry, as a text-based AI, I am unable to view or interpret graphs or images at this moment. However, I can tell you how to find the period of a pendulum based on a graph. The period of a pendulum is the time taken for it to complete one full oscillation - from starting point, to extreme, back through the starting point, to the other extreme, and back to the starting point again. On a position vs time graph, you can find this by finding the time difference between two successive points where the pendulum is at the same position and moving in the same direction (going to the right, or going to the left), which represents one complete oscillation. Please measure the distance along the time axis (usually the horizontal axis) between these two points to get the period of the pendulum.
