to measure wavelength and other wave characters
The Michelson Interferometer is used to create an interference pattern by splitting a beam of light into two paths. This device has several important scientific applications for experimentation.
He is the inventorof the Michelson interferometer.
a compensating plate is used in michelson interferometer to compensate the additional path difference of ray 1
The mirrors are perfectly perpendicular
In michelson interferometer experiment, when we see the fringe pattern ,it depends on the angle in which our eye see it. This is due to the angle theta between the eye and and fringe pattern. The second reason is the factor d, the distance between the mirrors M1 amd M2.
The Michelson device operates on Light waves. It is not a sound apparatus. One cannot use a telescope to analyze sounds, right?
In michelson interferometer the mirros are perpendicular and because of our eye viewed direction and angle theta the fringes are circular
two fringes .... since each half a wavelength distance corresponds to a fringe change!
To get a double image, which is then focused until one gets coincidence. Sextants, some camera rangefinders, etc make use of this beam-splitting principle.
The Michelson Interferometer was invented by Albert Michelson , who was pre-occupied with the discovery of the Speed of Light. This was not the original purpose of the device, however. it splits two light beams and then brings them into coincidence. In a sense this is not too different from a Stigmometer or split-image range finder used on some cameras. The Leica III Camera had one, I was shocked when a friend of mine let me use it- I saw Two Mr. Mclaughlins ( the school librarian) walking down the street, my friend said- bring the image into coincidence and the camera is focused!
The first American to be awarded the Nobel Prize in Physics was Albert A. Michelson. He was cited in 1907 for the invention of the interferometer, for spectroscopic investigations, and for measurements of the speed of light over a period of 50 years.
Larry Michelson's birth name is Lawrence Marvin Michelson.
