Question

A beam of unpolarised light of intensity I 0 is passed through a polaroid A and then through another polaroid B which is oriented so that its principle plane makes an angle of 45 o relative to that of A . The intensity of the emergent light is:, I 0 4, I 0 8, I 0, I 0 2

Relation between intensities is I R = I 0 2 cos 2 45 o = I 0 2 × 1 2 = I 0 4
