The physics of a pendulum wave

A pendulum wave is a physics demonstration involving multiple pendulums of increasing lengths that, when released simultaneously, create visual patterns of traveling and standing waves due to their differing oscillation periods. The longest pendulum completes a set number of oscillations, with each shorter pendulum completing one additional oscillation, leading to a mesmerizing display of synchronized motion that cycles back to the starting condition.

The physics of a pendulum wave

A pendulum wave demo of independent simple harmonic oscillators.

Each pendulum oscillates with its own period, T = 2π √(L/g), where L represents the string's length and g denotes gravity. The lengths are meticulously selected such that their frequencies maintain small-integer ratios.

As they gradually desynchronize, the resulting phase differences generate the captivating "wave" illusion you observe. Ultimately, they realign after approximately two to three minutes. It's a classic physics demonstration!

How To Make A Pendulum Wave (Science Experiment / Physics Toy)

For this project I show how to make make a pendulum wave, an interesting science/physics experiment where a series of pendulums is measured so that each one ...

Physics can be so neat and exciting =)

I was just far to entertained by this.  This is a pendulum wave created by bowling balls hung from varying lengths.  Jeff Goodman from Appalachian State University built it so that all the balls would swing back together at 2:40. In that time, the ball on the longest pendulum swings back and forth 50 times.  The next ball swings 51 times.  The next 52.  All the was down to the ball on the shortest pendulum, which swings 65 times. (If you check out their description on YouTube, they note a bit more on how it works and why theirs is not perfect.) Check out this other video of a slightly more accurate wave!

A mesmerizing pendulum wave demonstration with 16 bowling balls in a North Carolina forest

If you’ve ever been to a science museum or taken a physics class, you’ve probably encountered an example of a pendulum wave. This video shows a large-scale pendulum wave contraption built on private property in the mountains of North Carolina, near Burnsville. The mechanism relies on 16 precisely hung bowling balls on a wooden frame that swing in hypnotic patterns for a cycle of about 2 minute and 40 seconds.
