Light is incident from medium 1 to medium 2 at Brewster's angle equal to 55.4°, and transmitted angle is 34.6°, the permeability of medium 2 is 3/4. 1- Calculate refractive indices for medium land medium 2. 2- Calculate the reflection coefficient for s-polarized. 3- Reflection coefficient for p- polarized.

4. Sunlight (unpolarised light) is reflected from Liverpool's Canning half-tide dock on a day where the water's surface is smooth and still. The water is salty, with a refractive index of 1.36. (i) For what angle of incidence is the reflected light completely polarised (Brewster angle)? (ii) At this incidence angle, what is the corresponding angle of refraction? (iii) How would your answers change if the sea water was replaced with fresh water?
