A soap film (n = 1.33) is formed in a loop of wire that is mounted vertically is not exactly uniform in thickness because of its weight, but wedge-shaped in cross section. When the film is illuminated with the orange light of wavelength 630 nm, one sees that a distance of 2.60 cm separates two bright fringes that are 4 orders apart. By how much does the film differ in thickness over this distance? in mico meters.
