2. (a) Describe Brewster's angle for a diamond submerged in water. (2.5 marks) (b) Explain the advantage of polarized sunglasses over plain tinted sunglasess. (2.5 marks) (c) A series of polarizers are each rotated 10° from the previous polarizer. Unpolarized light is incident on this series of polarizers. Calculate the total polarizers that light have to go through before achieving 1/5 of its original intensity. (3 marks) (d) Unpolarized light of Io passes through six successive polaroid sheets each of whose axis makes a 35° angle with previous one. Find the intensity of the transmitted beam. (2.5 marks)
