Spherical and Chromatic Aberrations

Spherical aberration and chromatic aberration are briefly discussed. A converging lens is placed in front of a light source and parallel rays are projected onto the blackboard. These rays demonstrate both spherical and chromatic aberration. The aberrations are enhanced when the lens is replaced with a semicircular piece of plastic.
