Fringes are observed due to monochromatic light in a Michelson interferometer. When the
movable mirror is translated by 0.07 mm, a shift of 300 fringes is observed. What is the
wavelength of the light? What displacement of the fringe system takes place when a flake of
glass of index 1.51 and 0.004 mm thickness is placed in one arm of the interferometer? (Assume
that the light beam is normal to the glass surface.)
