Glass can be coated with a thin material as an antireflective coating. As per the image below, if the antireflective coating has a refractive index of n1 = 1.6 and the glass has a refractive index of n2 = 1.9, what is the smallest thickness (t) of antireflective coating required to provide minimum reflection from light of wavelength 500 nm normally incident on the glass? 500 nm n1 n2 t Glass can be coated with a thin material as an antireflective coating.
