Pendulum Wave

Experiment no.: 5.5.13
Wellenpendel New since 02/25
The pendulum wave consists of 15 pendulums of different lengths. The lengths of the pendulums are set such that in a given time t (here 70 seconds), the first pendulum completes n oscillations (here 46), and each subsequent one completes one more oscillation than the previous.
The choice of these pendulum lengths ensures that waves form between the seemingly chaotic pendulum movements. It is also well observeable that after t/2 (here 35 seconds), one half of the pendulums move in exactly the opposite direction to the other half.
