A parallel beam of white light falls from air on a thin film whose refractive index is `sqrt ( 3)` . The medium on both sides of the film is air. The angle of incdidence is `60^(@)`. Find the minimum film thickness if reflected light is most intense for `lambda" = 600 nm"`.

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 most intensively? (tan53^@ =4//3)

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)

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)

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 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 S4 T z reflects the light ?
