This tutorial explains how the time period of a pendulum depends on its length.

The time period of a pendulum is the time taken for the suspended mass (bob) to swing one way and then back to where it started.

A more accurate way to find the period of a pendulum is to time 20 swings (back and forth) and then divide that that by 20 to find the time taken for one complete oscillation.

If you increase the length of a simple pendulum, it's time period will also increase. However, this is not a directly proportional relationship.

If you quadruple the length of the pendulum, then the time period will DOUBLE.

More advanced: In other words, the time period is proportional to the square root of the pendulum length. The actual mathematical relationship is T = 2π√(L/g) where L is the length and g is the gravitational field strength (9.81 N/kg on Earth).
