The Michelson interferometer is an optical device that splits a beam of light into two paths, reflects them back, and recombines them to create an interference pattern. By analyzing these patterns, precise measurements of the wavelength of light and the refractive index of air can. Interferometers generally are used to measure very small displacements by using the wave property of light (or other radiation e. They measure changes of the interference pattern when waves with different phases overlap. Using a beam splitter, a light source is split into two arms.
