A film of oil of index of refraction n = 1.43 floats on water (n = 1.33). When illuminated with white light at normal incidence, light of wavelengths 658 and 470 nm is predominant in the reflected light. Determine the minimum possible thickness of the oil film (in nanometers). The ANSWER is 575 nm, but I can't seem to do the right work in order to get the right answer. Please help!
