About Michaelson Interferometer
Michaelson Interferometer is a precision instrument that produces interference fringes by splitting a light beam into two parts and then recombining them after they have travelled different optical paths. It finds application in measurement of small displacements. It can also be used to determine the wavelength of an unknown optical source
