Question

The refractive index of water for visible light can be taken as n = 1.33. (a) What is the (irradiance) reflectivity R(0 = 0) for normal incidence from a flat

water surface? (b) What is Brewster's angle OB in air for a flat water surface? (c) What is the (irradiance) reflectivity RTE(OB) for transverse-electric linear polarised light at Brewster's angle for a flat water surface?
