ID Code: G1-82
Purpose: Create waves in a very dramatic way using a series of fifteen carefully adjusted independent pendula.
Description: After the pendula are started into oscillation with the same 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. This is a GREAT demonstration - takes about one minute.
Availability: Available

Here's a fun animation, modeling springs instead of pendula: physics.bu.edu/~duffy/HTML5/spring_wave.html
