A thin air film is between two points A and B. When light of wavelength 5400 Å is used, 5 fringes appear between the two points. Find the difference in the thickness of the film between the two points.

On introducing a thin film in the path of one of the two interfering beam, the central fringe will shift by one fringe width if mu=1.5 , the thickness of the film is (wavelength of monochromatic light is lamda )

When the plastic thin film of refractive index 1.45 is placed in the path of one of the interfering waves then the central fringe is displaced through width of five fringes.The thickness of the film will be ,if the wavelength of light is 5890Å

White light reflected from a soap film (Refractive index =1.5 ) has a maxima at 600 mm and a minima at 450 nm at with no minimum in between. Then, the thickness of the film is

White light reflected at normal incidence from a soap film has minima at 6500Å and maxima at 7500Å in the visible region without minimum in between. If mu is (5)/(3) for the thin film, thickness of the film is

If wavelength 4500 Å and 6000 Å are found to be missing in the reflected spectrum in thin air film interference, the thickness of the film for normal incidence is nearly
