A soap film (n = 1.33) is 475 nm thick and lies on a glass plate (n = 1.52). Sunlight, whose wavelengths (in vacuum) extend from 380 to 750 nm, travels during the air and strikes the film perpendicularly. For which wavelength(s) in this range does destructive interference reason the film to look dark in reflected light?
