Our Ripple Tank/Wave Generator is designed specifically for use with an overhead projector. You can show your entire class experiments demonstrating wave propagation, reflection, diffraction, frequency-wavelength-velocity relationships and interference and phase differences. All of these general wave phenomena become much more dramatic when projected on a screen. The package includes the specially designed ripple tank, a wave generator and four barriers. The tank is clear plastic and measures 30 x 33cm. The slightly beveled sides eliminate the need for dampers. The sides have also been built up to make it easier to handle the tank when full. Our variable-phase wave generator is housed in a sturdy aluminum case with a 20cm steel rod extending through the back for simple attachment to a ring stand. Two point sources produce circular waves from one or two of four possible positioning points. A flat wave source is also supplied. Wave frequency can be varied from 3 to 20 per second using a variable DC power supply or external rheostat; frequency is 7 per second using a 1.5V dry cell. Includes a flat barrier, a curved barrie, and two barriers for producing a slit. CSA approved.
