About This Product

Turning the crank sends a wave along the row of pulleys slowly enough to follow by eye, so students can point to a crest, a trough or a compression and see how phase changes from one pulley to the next. It is used to explain wavelength, amplitude and the difference between transverse and longitudinal waves. Educational Instrument can arrange export supply of the Wave Motion Apparatus – 24 Pulleys to Mongolia, Oman, Jordan, Japan and Uzbekistan.

Frequently Asked Questions

How is the Wave Motion Apparatus – 24 Pulleys operated?

By a manual rotary crank. The crank turns graduated eccentric cams that move the 24 pulleys in sequence.
