3 18 4 4 O 3 In double slit experiment fringes are obtained using light of wavelength 4800 A One slit is covered with a thin glass film of refractive index 1 4 and another slit is covered by a film of same thickness but refractive index 1 7 By doing so the central fringe is shifted to fifth bright fringe in the original pattern The thickness of glass film is 1 2 x 10 mm 3 6 x 10 mm 3 2 4 x 10 mm 4 8 x 10 mm 3
