WAVE GENERATING APPARATUS FOR STUDY OF WAVE PHENOMENA

摘要

A wave generating apparatus particularly adapted for use in studying wave phenomena having a plurality of wave source means mounted above a ripple tank and reciprocated vertically by a pair of pivotally mounted parallel rocker arm means to produce waves in the surface of the fluid in the ripple tank. The means driving the rocker arms are adjustable with respect to the rocker arms to vary the amplitude of the waves produced and may be regulated by control means in electrical communication with them to vary the frequency and phase of the waves produced. The bottom of the ripple tank is sloped upwardly from its center to effectively damp the waves in at least one direction. The wave generator and ripple tank may be used in combination with an overhead projector or an overhead light source so that images of the waves produced are projected upon an easily visible plane surface.
