An anti-reflection (AR) coating is often applied to the surface of eye- glass lenses in order to reduce reflections. Consider a lens made of glass with a dielectric constant = 2.3 In order to achieve total transmis- sion from air into the glass lens a dielectric coating is applied to the glass surface. We would like to design an AR coating that will trans- mit blue light at frequency 650 THz (1THz = 1 × 10¹2Hz). Determine the following: (a) ( the required dielectric constant, er, of the coating layer. (b) the minimum thickness (in meters) for the coating layer.
