The ripple tank is a device to illustrate the laws which govern all wave phenomenon using ripples on the surface of water as the prototypes of all transverse waves. Ripple tank illustrates important wave motions like rectilinear and circular. It can also demonstrate refraction, diffraction and interference of water waves. The apparatus consists of a framed tray with a plexi glass base and detachable legs. A pair of support rods with clamps is provided which can be attached to the sides of the tank and used to carry the wave generating system. The ripples are produced by a small 1.5 to 4.5V D.C. electric motor mounted at the centre of a wooden wave generator bar with a row of holes to mount the spherical dippers supplied. It is recommended that the power supply unit is used as this has been specially designed for use with the ripple tank. It has continuously variable D.C.. output so that the speed of the motor and hence the frequency of the ripples may be varied. One white card sheet may be placed on the floor underneath the tank as a screen to receive the wave pattern shadows. Tank can be used with an overhead projector. Size of the tank 500 mm x 500mm (Approx.)
