WebIn interferometry experiments such as the Michelson–Morley experiment, a fringe shift is the behavior of a pattern of “fringes” when the phase relationship between the component sources change.. A fringe pattern can be created in a number of ways but the stable fringe pattern found in the Michelson type interferometers is caused by the separation of the …
WebStep 3: Multiply the distance from the center of the central fringe to the first minimum ( y1 y 1 ) by 2 to get the total width of the central fringe. 2y1 =2(2.75×10−3 m) = 5.5×10−3 m 2 y 1 ...
