A 5 mm thick non-magnetic glass plate (ɛ, = 2.56) has air on both sides. Air Glass Air Green Light &, = 2.56 5 mm a) If the green light (1, = 0.52 µm) comes perpendicular to this glass plate from the left side, what percentage of the incoming power is reflected back? b) In order to prevent the reflections occurring in the case of a, a thin film that prevents reflection will be covered on both sides of the glass. What should be the relative conductivity (ɛ,) and thickness of this film to be coated?
