WebThe Michelson interferometer (invented by the American physicist Albert A. Michelson, 1852–1931) is a precision instrument that produces interference fringes by splitting a light beam into two parts and then recombining them after they have traveled different optical paths. Figure 3.16 depicts the interferometer and the path of a light beam from a single … Webwhere n is the number of bright fringes, m is the order of the fringe, lambda is the wavelength of light, L is the distance from the grating to the screen, and w is the width of the grating.
