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 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?

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 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 :

A parallel beam of white light falls on a thin film whose refractive index is equal to 4//3 . The angle of incidence i=53^(@) What must be the minimum film thickness, if the reflected light is to be coloured yellow (lambda "of yellow" =0.6mum) most intensity ? (tan 53^(@)=4//3)
