written by Michael Fowler and Jacquie Hui Wan Ching

This simple animation illustrates the principle of time dilation, the phenomenon in which a clock that is moving relative to an observer is measured to run more slowly by that observer compared to a clock at rest. The concept of time dilation is central to a study of special relativity, and has been experimentally confirmed many times. This simulation consists of two light clocks, one at rest and the other moving at a fraction of the speed of light. The user can change the speed of the moving clock to see that the time dilation effect is reciprocal.
