Dispersion in a Prism

(The more visually impressive version) A rainbow spectrum is produced on a projection screen by passing light from a bright source through a glass prism. A suitable light source is a lantern projector, and an image of the slit is focused onto the screen before introducing the prism into the path of light.

(Blackboard Optics Kit version) A large Lucite prism is mounted on the board using either the magnetic or the suction cup mounting bracket. A single slit light source produces a ribbon beam of light across the board and through the prism. The beam is seen to spread out as it passes through the prism and back out into the ambient medium. A hand-held screen can be used to make the dispersed colors more visible.
