Colored Interference Patterns

AIM

The purpose of this project is to show a thin layer of air trapped between two pieces of Plexiglas produces rainbow-colored interference patterns. When light hits two separated transparent surfaces, some of the light will be reflected from each surface. If the distance between surfaces is a multiple of half or whole wavelengths of light, constructive & destructive interference will produce an interference pattern.
