please explain it through the diagram that if a third polari zer she is placed in between the A and B then if the angle between a and b is theta then how the angle between Ba nd C is also theta Unpolarized light of intensity I is incident on a system of two polarizes A followed by B The intensity of emergent light is I 2 If a third polarizer C is placed between A and B the intensity of emergent light is reduced to I 3 The angle between the polarizers A and C is 0 Then A B C D cos 0 cos 0 1 4 cos 8 1 4 1 2 3 2 2
