The Demonstration Wave Machine allows for easily visible demonstrations that show the behavior and properties of transverse waves.
The motion of the wave is demonstrated by a chain of 73 steel pendulum bars each soldered at their mid-point along a rod spring that can be subjected to torsion. The ends of the bars are painted on one side in fluorescent paint and on the other side with white paint. A damping mechanism is also supplied and a retaining clamp on a stem for demonstrating reflections at a fixed end. The machine is mounted on a foldable steel base.
Number of bars: 73
Length of bars: 460 mm
Total length: 920 mm
