SW-2697 - ESAW Ripple Tank Apparatus 

A specially designed versatile apparatus for the investigation of the wave properties, such as wave propagaon, reflecon, refracon, diffraction, and interference. Permits demonstration with an overhead projector or use as a free standing bench model, allowing investigations to be carried out directly. Comprises a rectangular plastic tank with a clear boom and sloped sides incorporating beach effect to eliminate unwanted reflections. The tank has four detachable legs mounted at its underside at the corners with a hole in the clear tray for water drainage. One end of the tank has clamps for supporting a lamp holder with a pair of clamps on each side for mounting rippler support rods. Rippler assembly comprises of a rectangular plastic rod with a series of holes suitable for mounting spherical dippers and a low voltage DC motor having eccentric cam attached to its shaft to produce an oscillatory moon. Supplied complete with the following accessories.

•  Illuminant Assembly
