DUAL PURPOSE RIPPLE TANK |
Code: GP - 566.2 |
It is used as a demonstration model with an overhead projector.
Comprises a steel frame with an acrylic window. The frame is shared to form beaches on all sides to minimise unwanted reflections and fits neatly onto an overhead projector. The underside of the frame has threaded metal inserts to take the four legs provided enabling the required. Facilities are provided for mounting the ripple tank illuminant for this purpose. A gantry is supplied for supporting a motor beam, the height of which is easily adjustable allowing it to be positioned for maximum effect. Ripples are produced by a small 1.5V to 4.5V D.C. motor mounted on the plastic beam of 240mm length. A standard cam is fitted to the motor spindle to give an oscillatory motion and row of nine holes in the beam are for mounting the spherical dippers for production of circular ripples.
The full set of apparatus comprises:
1 Ripple tank 330x330x35mm deep, 1 Gantry complete with beam, 4.5V D.C. motor and fittings, 4 screw in legs for bench mounting, 1 illuminant support rod, 2 spherical dippers, 1 Glass plate and spacers for refraction. 1 Dropper, 10 Suspension bands, 2 Leveling wedges.
