A thin film of polystyrene is used as an antireflective coating for fabulite (known as the substrate). The index of refraction of the polystyrene is 1.49, and the index of refraction of the fabulite is 2.409. (Figure 1) Figure < 1 of 1 Air n = 1.49 n = 2.409 Light. rays ||| Polystyrene Fabulite Constants Part A What is the minimum thickness of film required?
