The Advanced Projection Ripple Tank is a comprehensive
system for demonstrating basic wave phenomena using water
waves. A horizontal glass plate is mounted in a watertight frame
with foam beaches around the perimeter to suppress unwanted
wave reflections.
This tank is mounted on three tall legs with an angled mirror
beneath the glass plate. A translucent screen is fitted to the front
of the apparatus to display the projected image. A stray light
shield can be placed around the back and sides of the apparatus
to prevent ambient light from reaching the screen.
In use, a pool of water a few millimeters deep is filled into the
tank. A ripple generator for mounting and energizing ripplers
is fitted to one side of the tank and an LED stroboscope lamp
is adjustably mounted above the glass plate on a gooseneck
support to provide the projection light. The ripple generator and
the LED stroboscope lamp are both driven by a Wave Monitor
control unit that synchronizes the wave generator€™s oscillations
with the stroboscope flashes to produce a stationary projected
image.
The wave generator can also by operated asynchronously,
allowing the stroboscope flash frequency to be varied while
the wave generator frequency remains fixed. This generates a
moving projected image of variable speed.
The included accessory set contains a series of five different
ripplers (two of each), a pair of acrylic blocks, a barrier with slits,
a clear foil with a printed grid, a plastic dropper, and a metric
ruler
