Draw a graph that shows the dependence of intensity of transmitted light on the angie between Polariser and analyser.

(a) State law of Malus. (b) Draw a graph showing the variation of intensity (I) of polarised light transmitted by an analyser with angle (theta) between polariser and analyser. (c ) What is the value of refractive index of a medium of polarising angle 60^(@) ?

What is is plane polarised light ? Two polaroids are placed at 90^(@) to each other and the transmitted intensity is zero. What happens when one more polaroid is placed between these two, bisecting the angle betweeen them ? How will the intensity of transmitted light vary on further rotating the third polaroid ? (b) If a light beam shows no intensity variation when trasmitted through a polaroid which is rotated, does it mean that the light is un-polarised ? Explain briefly.
