This unit can be used for dual purpose demonstration as it can also be mounted on top of a overhead projector for a larger view of straight and circular wave forms it generates. Comes complete with all the accessories required to perform investigations and experiments into reflection, refraction and interference effects. The tank is frame is made from tough plastic which surrounds the clear perspex center base. A low voltage power regulator is required which provides continuously variable D.C. output so that the speed of the motor and the frequency of the ripples may be regulated (not included).
Overall size of tank 600x520x55mm deep. Support rod with 'G' clamps are provided for use of carrying waves generating system. Four metal barriers ( reflectors) consisting of a pair of straight barrier 150x25mm chord barrier of 215mm chord length x 25mm high and a short, straight barrier. Ripples are produced by a small 1.5 to 4.5V DC electric motor mounted on a 330mm wooden bar having a row of holes to mount spherical dipper, complete with 12 V illumination with clamp.
