Ripple Tank Kit

An overhead projector type ripple tank for demonstration of various wave phenomena, including reflection, refraction, diffraction, and interference. The unit comprises a shallow 40 x 40 cm tank with a scratch-resistant acrylic window on the bottom, supported by four adjustable legs. Two arms on the side hold an eccentric motor and bar assembly, onto which either two point dippers, or a plane-wave dipper can be attached. The motor and bar assembly is suspended by springs so the vibration is not transmitted to the tank. A bright point light source is held overhead, which shines down through the water in the tank, and casts a shadow of the waves on the bench below. The following accessories are included: Concave, convex, rectangular Perspex plates; curved reflector; two large one small barriers; two point dippers; hand stroboscope; banana leads; instructions. The motor requires continuously variable 0-5 V DC power supply, and the lamp requires 12 V AC supply. Alternatively, the ripple tank can be driven by the SO180324 ripple tank LED driver.
