A parallel beam of light of wavelength 560 nm falls on a thin film of oil (refractive index = 1.4). What should be the minimum thickness of the film so that it strongly transmit the light ?

A parallel beam of light of wavelenght 560 nm falls on a film of oil (refractive index =1.4 ). What should be the minimum thickness of the film so that it weakly transmits the light ?

A parallel beam of white of white light falls on a thin film whose refractive index is 1.33. If angle of incidence is 52^(@) then thickness of the film for the reflected light to be coloured yellow (lambda=6000Å) most intensively must be :

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.

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?

A light of wavelength 5890Å falls normally on a thin air film. The minimum thickness of the film such that the film appears dark in reflected light is
