A film of oil lies on wet pavement. The refractive index of the oil surpasses that of the water. The film has the minimum nonzero thickness such that it appears dark due to destructive interference when viewed in red light (wavelength = 660 nm in vacuum). Assuming that the visible spectrum extends from 380 to 750 nm, what are the visible wavelengths (in vacuum) for which the film will appear bright due to constructive interference?
