Ripple Tanks
Ripple Tanks
Ripple tanks are shallow glass water tanks that are used to create a variety of wave patterns to illustrate wavelength, velocity and frequency. Ripple tanks can also demonstrate interference, diffraction, refraction and reflection. Ripple tanks may be illuminated from above, allowing light to shine through the water, while some smaller tanks may fit onto overhead projectors to be illuminated from below. Ripples from the tank, once illuminated, show up on the screen as shadows.
