Modified Michelson Interferometer Experimental Setup Download This step by step guide covers required parts, setup instructions, and alignment tips for producing interference fringes to measure distance, wavelength, or refractive index changes in an accessible lab environment. One of his instruments was the michelson interferometer. the michelson interferometer produces interference fringes by splitting a beam of monochromatic light so that one beam strikes a fixed mirror and the other a movable mirror.
Modified Michelson Interferometer Experimental Setup Download The purpose of this experiment is to give you some practice in assembling, aligning and using a michelson interferometer to measure the index of refraction of air. the principle of the michelson interferometer is shown in fig. 16.1. Michelson's interferometer is based on the principle of division of amplitude and interference of light waves. it consists of two perpendicular plane mirrors m₁ and m₂, one of which (m₂) can be moved precisely with a micrometer screw. The michelson interferometer is a remarkable instrument with significant applications in both optics and astrophysics. for instance, in optics, the setup can be used to study interference phenomena and measure the wavelength of light with precision. in astrophysics, interferometry is used to enhance the reso lution of telescopes. The objective of this experiment is to demonstrate the interference pattern obtained from combining coherent monochromatic light beams using a michelson interferometer setup. you will ultimately derive the wavelength of the light source from your measured interference pattern.

The history of interferometers began in 1881 with a setup created by albert a. michelson (for which this setup is named) which in 1887 resulted in the michelson–morley experiment (performed together with edward w. morley). Interferometry is a central building block for many optics measurements and a versatile tool in the laser lab. here we describe the general working principle and give a systematic and simple setup and alignment procedure. This document provides instructions for setting up and using a michelson interferometer to measure the wavelength of a he ne laser and the refractive index of a glass plate. In this experiment, you will use a michelson interferometer to determine the wavelength of laser light, as well as to investigate the index of refraction of air and how it is affected by changes in pressure. figure 1 is a diagram of the apparatus, the pasco model os 8501 interferometer.
