Answer:

Explanation:

 The Michelson interferometer was invented by an American physicist A.A.Michelson (1852-1931). The Michelson interferometer played an interesting role in the history of science during the latter part of the nineteenth century. It has a great scientific importance and had an equally important role in establishing high precision standards of the unit of length. In contrast to the Young's double slit experiment for producing interference fringes which make use of light from two narrow sources, the Michelson interferometer uses light from broad, spread source (extended source).

   The essential features of a Michelson interferometer are shown schematically in figure given below:
