Demonstration of two-beam interference in a Michelson interferometer with collimated beams

Demonstration of the effect of path length difference (0-100 cm) on fringe contrast

Demonstration of the spectrum of the light source, in this case, a multilongitudinal mode He-Ne laser

Relationship between fringe contrast, path length difference, and spectrum of the light source
