What is the thinnest film that will highly reflect near-ultraviolet light of wavelength 350 nm?

A thin film with index of refraction n-film = 1.38 is used to coat a lens, which has n-lens = 1.50. What is the thinnest film that will highly reflect near-ultraviolet light of wavelength 350 nm? What is the thinnest film that will minimize reflection of 700 nm light?|||AuAg will help as well as aluminite. Light is a frequency wave, you will not get a perfect answer until you better understand Gauss
