The Advanced Projection Ripple Tank by United Scientific is a free-standing wave demonstration system with a glass-plate tank, angled mirror, and translucent screen. A Wave Monitor control unit synchronizes the ripple generator with an LED stroboscope, freezing waves into a stationary image or setting them moving at a variable apparent speed. It includes five pairs of ripplers, acrylic blocks, a slit barrier, and a grid foil. Physics teachers use it for measurable wave demonstrations without an overhead projector.
