Ripple Tank
A wooden framed tray with
sloping position inside to minimise unwanted reflection from the sides
of the tank; with perspex plastic base & 4 detachable legs. Size of
the tray 650 x 520 x 55 mm. Support rod with G clamps are provided
for using to carry waves generating system. Four metal barriers (
reflectors ) consisting of a pair of straight barriers 150 x 25 mm
chord barrier of 215 mm chord length, 25 mm high & a short straight
barrier. Ripples are produced by a small 1.5 to 4.5 V DC electric motor
mounted on a 330 mm wooden bar having a row of holes to mount spherical
dipper. Complete with 12 V illuminator with clamp.
Dual Purpose Ripple Tank
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 & fits neatly onto an
overhead projector. The undersides of the frame has threaded metal
inserts to take the four legs provided enabling the tank to be used as
a free standing beach model, if 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 1.5 to 4.5 V DC motor mounted on the plastic beam
of 240 mm length. A standard cam is fitted to the motor spindle to give
an oscillatory motion & row of nine holes in the beam are for
mounting the spherical dippers for production of circular ripples.
