It is necessary to coat a glass lens with a non-reflecting layer.If the wavelength of the light in the coating is `lambda` ,the best choice is a layer of material having an index of refraction between those of glass and air and a thickness of

The wavelength of green light in air and in glass is 5300 Å and 3533 Å. The refractive index of glass is

A thick glass slab (mu= 1.5) is to be viewed in reflected white light. It is proposed to coat the slab with a thin layer of a material having refractive index 1.3 so that the wavelength 6000 Å os suppressed. Find the minimum thickness of the coating required.
