Ripple Tank
PRODUCT DETAILS
This apparatus allows the study of wave propagation on the surface of a liquid and, in particular, phenomena of reflection, refraction, diffraction, and interference. The waves on the liquid surface of the tank are produced by a wave generator through a periodic jet of air or a manual variation of the immersion depth of the plane agitator. The water surface is illuminated by a light beam reflected by an inclined mirror placed under the tank. The beam, produced by a halogen lamp is periodically interrupted with the same wave generated frequency. The crests and troughs of the waves that propagate on the surface of the liquid behave, respectively, like convergent and divergent lenses, thus creating areas characterized by an intense luminosity alternating with areas of less luminosity. The images are projected on a screen placed in front of the device. The necessary measurements can be performed on the screen, keeping in consideration the magnifying effect of the projection. Tank components are fabricated of heavy-gauge aluminum and plastic parts. Grade 9 and up.
