G1-83: PENDULUM WAVES - COMMERCIAL VERSION

ID Code: G1-83
Purpose: Create waves in a very dramatic way using a series of carefully adjusted pendula of various lengths.
Description: This is a commercial version of our demonstration G1-82: Pendulum Waves. After the pendula are started into oscillation in phase, they pass through a series of various standing wave and traveling wave patterns, finally returning to their initial mode, in which they were all in phase.
Availability: Available
