Is there more to light than meets the eye? Does a green filter change white light into green light? What color of light is observed when blue and yellow filters are mixed? This demonstration uses a holographic diffraction grating and an overhead projector to produce a large, sharp rainbow of color. The large spectrum allows you to demonstrate the true nature of color and light and address common misconceptions related to the perception of color.
