Our disscusssion of the techniques for determining cosntructive and destructive by reflection from a thin film in air has been confused to rays striking the film a nearly the normal incidence.Assume that a ray is incident at an angle of `45^(@)` (relative to the normal ) on a film with an index of refraction of `sqrt(2)`.Calculate the minimum thickness fro constructive interference for light of wavelength `600nm`.

A thin film of thickness t and index of refractive 1.33 coats a glass with index of refraction 1.50 .What is the least thickness t that will strong refelct light with wavelength 600nm incident normally?

White light is incident normally on a thin glass plate of refractive index 1.5. Calculate the minimum thickness of the film for which the wavelength 4200 Å is absent for the reflected light.

When light rays are incident on a prism at an angle of 45^(@) , the minimum deviation is obtained. If refractive index of the material of prism is sqrt(2) , then the angle of prism will be

Blue light of wavelength 480 nm is most strongly reflected off a thin film of oil on a glass slab when viewed near normal incidence. Assuming that the index of refraction of the oil is 1.2 and that of the glass is 1.6, what is the minimum thickness of the oil film (other then zero)?

The refractive index of water relative to air is 5/3. A ray of light passing from water into air is incident at the interface at an angle of 32^(@) with the normal. What angle does the refreacted ray make with the normal?

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
