Wave Pendulum

Wave Pendulum

The pendulum, a harmonic oscillator, can be found in various fields such as quantum physics, electronics, and even acoustics. The speed of a pendulum does not depend on its mass, which seems counter-intuitive at first.

A longer pendulum swings slower than a shorter one, its speed depends only on its length. For the wave pendulum, the lengths of the single pendula have to be tuned very precisely, aiming for harmony. In this setup, the frequencies have to be integer multiples of each other. In this way the wave pendulum is very similar to an instrument. When the wave pendulum swings, it lapses from order into chaos, then back into order, creating a fascinating, mesmerising rhythm.
