Pendulum Wave

What you’re seeing

A pendulum-wave: many pendulums with slightly different lengths start in phase and drift, creating mesmerizing wave patterns.

How it works (in short)

Each length gives a slightly different period. As phases slip, constructive/destructive alignments produce traveling and beating patterns.

Setup and gear

• Rigid top bar/frame with evenly spaced hang points
• Strings and weights (pendulum bobs)
• Measured lengths with small increments between pendulums

Safety notes

• Secure the frame, keep clear of moving masses.
• Use low-friction pivots for clean motion.
