The Michelson interferometer operates on the principle of interference, where two beams of light combine to produce a pattern of constructive and destructive interference. It is a fundamental optical device used to measure wavelength, refractive index, and other optical properties with high precision. The core mechanism involves splitting a single beam of monochromatic light into two paths, manipulating them, and then recombining the beams to form interference fringes.

Principle of Michelson Interferometer

The Michelson interferometer uses a beam splitter, typically a partially silvered mirror, to divide an incident light beam into two separate beams. These beams travel along two perpendicular arms of the ________ _______ ______ ____ ____ ______ ________.
