Engineers are testing a new thin-film coating whose index of refraction is less than that of glass. They deposit a 460-nm-thick layer on glass, then shine lasers on it. A red laser with a wavelength of 640 nm has no reflection at all, but a violet laser with a wavelength of 400 nm has a maximum reflection. How the coating behaves at other wavelengths is unknown. What is the coatings index of refraction?
