Acrylic Pendulum Wave Demonstrator

Item # 751669

Create waves of excitement for phase, beats, and frequency with a mesmerizing demo! Simultaneously release 9 pendulums to form a wave that dissipates before cycling back in phase to form the wave again. Each 2-line mount pendulum varies from slightly less to slightly more than 20 swings in 20 seconds. The rigid interlocking acrylic frame with installed offset tubing measures about 22” W x 19” H. Allow 40 min to assemble. Includes initiator stick and instructions.

Once the apparatus has been assembled, place the initiator stick against the pendulums from the back and uniformly displace them, then quickly remove the stick. All pendulums begin to swing in phase. Since the periods differ, the phase relationship between pendulums will change in a continuous fashion to make a compelling wave-like display. A great demonstration to introduce topics such as waves or pendulum motion. Use to reinforce vocabulary such as “period,” “phase,” “beats,” and “frequency.”
