There is a film of oil (n=1.52) on a wet pavement (n=1.33). the film has a minimum non-zero thickness such that it is dark when viewed in red light (wavelength = 660 nm in vacuum). Assuming that the visible light spectrum extends from 380nm to 750nm, what wavelength in vacuum will you see when you look at the film in broad daylight?

A soap film (n = 1.33) is 498 nm thick and lies on a glass plate...
A soap film (n = 1.33) is 498 nm thick and lies on a glass plate (n = 1.52). Sunlight, whose wavelengths (in vacuum) extend from 380 to 750 nm, travels through the air and strikes the film perpendicularly. For which wavelength(s) in this range does destructive interference cause the film to look dark in reflected light? To 3 significant figures
