Pendulum Wave Demo

Grades 6-12.

Simulates phases, beats, and frequencies in a captivating physics experiment for all ages! Features a clear acrylic stand with nine 7/8 in. steel ball pendulums, and comes with an initiator stick to help release all the pendulums simultaneously. When released, pendulums swing back and forth to create the effect of a changing transverse wave that cycles back to the beginning conditions. Great for demonstration and display! Includes teacher’s guide.
