A thin film coats a flat piece of glass. Sunlight falls almost perpendicularly on the thin film and reflects to your eyes. wavelength 501 nm is destructively interfered and eliminated. refractive index of film is 1.35 and glass is 1.78, determine watts from the sun that fall on the film. What color of light is missing from the incident light. what is the thickness of the film. How strong will the light be to evaporate 1 square mm of film?
