Michelson Interferometer Bms Education Subscribed 14 1k views 9 years ago here we use an old mi to measure the wavelength of hene light more. The michelson interferometer is a common configuration for optical interferometry and was invented by the american physicist albert abraham michelson in 1887. using a beam splitter, a light source is split into two arms.
Michelson Interferometer To compare the phases of the rays in the two arms we start from a point, say o, o ′, when the two were together and go to a point, say e, e, when they come together again. Yes, michelson's interferometer can be used to measure the refractive index of a gas. by placing a gas cell in one arm of the interferometer and evacuating it, the change in the optical path due to the introduction of gas will cause fringe shifts. 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 michelson interferometer is the best example of what is called an amplitude splitting interferometer. it was invented in1893 by albert michelson, to measure a standard meter in units of the wavelength of the red line of the cadmium spectrum.

Michelson interferometer is one of the most widely used experiment apparatus in the field of optics. the key components present in the michelson interferometer are a beam splitter, two. Taking a measurement for every single fringe would be extremely diicult but keeping track of exactly how many you have counted gets harder the more you do. a good balance would be to count 20 fringes, note the position of the micrometer; count another 20 fringes and note the new position; and so on. 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.
