# Michelson Interferometer

A modular mirror and beam-splitter system is used to set up and investigate the properties of an historically significant interferometer. Interference patterns are observed for three types of light sources: a laser, an incandescent lamp (white-light), and a sodium lamp. The yellow sodium D lines are used to illustrate the Fourier transform properties of the interferometer.
