Webhypothesis. Michelson's interferometer has become widely used for measuring the wavelength of light, for measuring extremely small distances, and for investigating optical media. Figure 1 shows a diagram of a Michelson interferometer. The beam of light from the laser strikes the beam-splitter, which reflects 50% of the incident Webused in a Michelson interferometer. The distance between the source and the beam splitter BS is L 0. The distances between the beam splitter and the mirrors of the interferometer are L 1 and L 2.
