Normally incident light passes through air (index of refraction = 1.000 ) and then passes through the oil and the refracted ray exits through the glass which has an index of refraction of n = 1.60 When illuminated with normally incident light, successive maxima in reflection are observed at wavelengths of 2, = 550.0nm and 2n = 450.0nm (these are air wavelengths). No maxima are observed between those two wavelengths. What is the thickness of the oil film?  Science Physics
