A thin transparent film of thickness 3000 `Å` and refractive index 1.5 ud deposited on a sheet made of a metal. Assuming normal incidence of light and also that the film is a plane parallel one, what will be the color of a pot made from this sheet when observed in white light?

By an anodizing process, a transparent film of aluminium oxide of thickness t = 250 nm and index of refraction n_(2) = 1.80 is deposited on a sheet of polished aluminium What is the color of utenslis made from this sheet with observer in white light? Assume normal incidence of the light.

A thin soap film of thickness 3 xxx 10^(-7)m and mu = 1.5 is spreaded on a glass surface. When white light is normally incident on this sheet, find the colour which will be reflected strongly by the film. [4500Å]

When white light is incident normally an oil film of thickness 10^-4 cm and refractive index. 1.4 then the wavelength which will not be seen in the reflected system of light is

A transparent thin film of uniform thickness and refractive index n_(1) =1.4 is coated on the convex spherical surface of radius R at one end of a long solid glass cylinder of refractive index n_(2) =1.5 , as shown in the figure. Rays of light parallel to the axis of the cylinder traversing through the film from air to glass get focused at distance f_(1) from the film, while rays of light traversing from glass to air get focused at distance f_(2) from the film, Then
