Consider a soap film that is the thinnest film that will produce a bright blue light when illuminated with the white light. The index of refraction of the soap film is 1.35 and the blue light is monochromatic with wavelength 41 1 nm. a) Calculate the thickness of the film if the soap covers a piece of crown glass with index of refraction of 1.52. [2 marks] 6 air nair = 1.00 soap film nfilm = 1.35 glass glass = 1.52 Suppose the reflections occur instead from the soap film on water with index of refraction of 1.33. Determine the thickness of the film on the water that will produce the same blue colour of reflected light. [2 marks] 7 19.
