Wave Machine, Powell’s
Catalogue No: 1120060
For demonstrating the movement of progressive transverse waves. Comprises a number of circular discs mounted equidistant from each others on a horizontal shaft in gradually varying degrees of eccentricity, with each disc having a vertical rod of same length supported on top and sliding up and down into a pair of guides. Complete assembly mounted on a metal base.

Wave Motion Demonstrator
Catalogue No: 1120108
An outstanding version of the classic wave machine. This device consists of a series of pendulums independently suspended on a common base and coupled together by long-light springs. Two modules are included, each with 43 pendulums, a damping unit with a paddle and water bath and a motor-powered eccentric driver for controlled excitation of waves. Coupling hardware is supplied so that the demonstrator can be used with either a single module or with both modules coupled to make a longer machine. The ends of the pendulums are colored bright yellow, while the rest of the machine is black, so the wave patterns are prominent and clearly visible. Basic phenomena in transverse wave propagation can be clearly shown. Using the damping module, running waves can be enerated to illustrate the concepts of wavelength and frequency. Standing wave patterns, wave reflection and superposition can be shown when the damping module is removed. A mechanical brake is also included so that all of the pendulums can be stopped instantaneously, freezing the
wave pattern in place for more detailed discussion. Waves can also be excited by hand.

Weight Box In A Plastic Case
Catalogue No: 2013250
Precisely designed set of masses comprising 1 x 500g, 1 x 200g, 2 x 100g, 1 x 50g, 1 x 20g, 2 x 10g, 1 x 5g, 2 x 2g and 1 x 1g (total 1000g) marked at their top for easy identification and placed in well designed moulded plastic box. All weights have a collar for convenient handling. An easily detachable plastic strip shields the small sized masses by preventing them from accidentally falling from their respective recesses.
