Pendulums dancing in harmony
What is it about?
The speed of a pendulum does not depend on its mass: longer pendulum swings slower than a shorter one, its speed depends only on its length.
The pendulum is a fundamental system in physics, its so-called harmonic oscillations find relevance in many different fields like quantum physics, electronics, and acoustics.
Details and Theory
For a wave pendulum, the lengths of the single pendula have to be tuned very precisely.
For the wave pendulum effect, the frequencies have to be integer multiples of each other. In this way the wave pendulum is very similar to an instrument.
