A row of pendulums with slightly different lengths. They drift in and out of phase, weaving traveling waves, then briefly snap back into sync.

Governing equation

T_{i} = 2 π L_{i} / g, T_{0} \approx 2.00 s, N = 18

Reading this result: Each of the 18 pendulums is set to a slightly different length, so its period drifts from the slowest (~2.00s, 30 swings per cycle) to the fastest (~0.61s, 98 swings per cycle). With a period spread of 4, the phases fan out into a traveling wave, dissolve into a chaos-looking scramble, and then all re-sync at the common 60-unit cycle before repeating. Wider spread reaches the disordered stage sooner; more pendulums makes the wave smoother.

About this simulation

The full Pendulum Wave tool models a skydiver's free fall with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
