This is intended to be used with a standard overhead projector to display, describe and discuss the visible spectrum of light and the role of various filters without the usual burden of special language and involved calculation. A continuous reference spectrum is projected as well as the spectrum of a filtering material. The answer to a yellow gel over-lapping a blue one is now obvious. Kit includes a large piece of holographic diffraction grating, a slit for the projector stage, more than 30 colored gels, and three special flasks for viewing a transparent colored liquid.
