Time period of a pendulum depends on its length | Oscillation| Physics

String up a pendulum, move the bob to one side and let go to set the pendulum into oscillations. Use a stopwatch to measure the time the pendulum takes to complete ten oscillations. Diving this time by 10 gives us the period of the pendulum i.e. the time taken to undergo one oscillation. Decrease the pendulum's length and repeat the above to get the new time period. We see that as the length becomes shorter, the time period decreases. This shows us that the length of a pendulum and its time period are related
