Paul Liu: Making your own pendulum wave machine
“Making your own pendulum wave machine This post is a continuation of a three part post started here. To make your own pendulum wave machine, you can see from the video that you just need to place 15 pendula or so beside each other at equal separations. What is hard to see however, is how long the length of string should be. Below we'll derive a function for you to calculate the lengths of each pendulum on your machine (or just scroll to the bottom to see some precalculated lengths). ”
