Two polaroids P1 and P2 are placed in a crossed position. Unpolarised light of intensity I0 is incident on P1. If P2 is rotated through an angle ө about the direction of propagation of light, keeping P1 fixed, plot the graph of intensity of light for 0⸰ < ө < 360⸰ which is (i) transmitted by P1, and (ii) transmitted by P2.
