Consider two polaroids A and B as shown. Unpolarised light is incident on polaroid A. Now, both the polaroids are rotated simultaneously by 180^\circ in same sense of rotation such that at every instant, their pass(transmission) axes always remain parallel to each other. During the rotation, intensity of transmitted light through polaroid {B}

Consider two polaroids A and B as shown. Unpolarised light is incident on polaroid A. Now, both the polaroids are rotated simultaneously by 180° in same sense of rotation such that at every instant, their pass(transmission) axes always remain parallel to each other. During the rotation, intensity of transmitted light through polaroid B
