3. A thin layer is deposited to a glass substrate. Their refractive indices are n = 1.3 and ng = 1.6, respectively.Determine the thickness of the layer if at normal incidence, it enhances reflection at 433 nm, and decreasesit when the wavelength of light is 520 nm. Are there other possible layer thicknesses that satisfy the abovecondition? At which wavelength does it enhance reflection if the incidence angle is 60°?
