Question 13 MarksWhat is the parallel and crossed arrangement of polaroid?AnswerArrangement of Polaroid : When unpolarized light passes through the polaroid, then the output light is polarized. Another polaroid is used for its analysis. When both the polaroids are parallel to each other, the intensity of the output light is maximum as shown in figure (a). If theFig. : Parallel arrangement Fig. : Crossed arrangement light is viewed by rotating the second polaroid by $90^{\circ}$ then the intensity of the output light is zero. This arrangement of polaroids is called crossed arrangement. In this arrangement the axes of both the polaroids remain perpendicular to each other. As shown in figure (b).View full question & answer→
