Light & Color

Color Removal

This exhibit takes a beam of white light, passes it through a prism to separate the colors, and projects the resultant colors on a screen. The visitor can place transparent colored filters in the white light beam and watch the spectrum to find out which colors are absorbed by the filter. A small portion of the white light bypasses the prism and is projected on a separate screen to allow the visitor to see the effects of the filter on white light in addition to its effects on the spectrum.
