(a) What is linearly polarised light. Describe briefly using a diagram how sunlight is polarised. (b) Unpolarised light is incident on a polaroid. How would the intensity of transmitted light change when the polaroid is rotated?

When unpolarized light is polarized with two polarizers, the intensity becomes I=Iocos2(θ)I=Iocos2(θ)(Malus's law). But when unpolarized light is polarized with only one polarizer, the intensity is reduced to half the intensity of the unpolarized light.
