Why compensatory plate is used in Michelson interferometer?

Compensating plate in Michelson interferometer is used to equalize the distance each beam travels through glass.

Why compensator plate is required?

With the reflective side of the beam splitter facing the source, the number of journeys through the glass is still 3 for one beam and 1 for the other, hence the need for a compensator plate to add two journeys through the glass remains.

What is meant by compensating plate?

[′käm·pən‚sād·iŋ ‚plāt] (optics) The first of two plates in a Brace compensator, which covers the entire field of view.

What is the purpose of compensator between the half silvered mirror and one of the mirror?

The purpose of a compensator is to make up for any path length differences in the two paths light travels in the interferometer. If the beamsplitter is a thinly silvered mirror, light reflecting off the silvered surface is deflected but not delayed.

What does the Michelson interferometer do?

A Michelson interferometer is used to measure the wavelength of light put through it. When the movable mirror is moved by exactly 0.100 mm, the number of fringes observed moving through is 316.

What is the working principle of Michelson interferometer?

State the principle and describe the construction and working of Michelson Interferometer. Principle: It works on the principle of interference of light by the division of amplitude in light from an extended source is divided into two parts of equal intensity by partial reflection and refraction.

What is a Michelson interferometer used for?

The Michelson interferometer and its modifications are used in the optical industry for testing lenses and prisms, for measuring index of refraction, and for examining minute details of surfaces (microtopographies). The instrument consists of a half-silvered mirror that divides a light beam into two equal parts,…

How does the Michelson interferometer work?

The Michelson interferometer works by splitting a beam of monochromatic light into two equal amplitude beams. One beam hits a fixed mirror and the other hits a movable mirror giving different beam lengths which converge on a detector screen giving an interference pattern.

What are the applications of Michelson interferometer?

Michelson interferometers can be used to measure the speed of light in different mediums, precisely measure the exact position of an object, break light up into a spectrum, test optical components, and to study wind and temperature patterns (especially in the upper atmosphere).
