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)?

A material having an index of refraction of 1.30 is used as an antireflective coating on a piece of glass (n = 1.50). What should be the minimum thickness of this film in order to minimize reflection of 500 nm light?

A film with index of refraction 1.50 coats a glass lens with index of refraction 1.80. What is the minimum thickness of the thin film that will strongly reflect light with wavelength 600 nm?

Find the minimum thickness of a film which wioll strongly relfect the ligth of wavelength 589 nm,when incident normally on it.the refractive index of the material of the film is 1.25.

A ray of light is incident at an angle of 45^@ (ralative to the normal) on a thin film of a liquid with an index of refraction of sqrt(2) . Assuming that the medium of both sides of the film is air, find the minimum thickness of the film required for constructive interference in the reflected light for sodium light of wavelenght 600 nm.
