10 1 Consider a light beam incident from air to a glass slab at Brewster s angle as shown in the figure P A polaroid is placed in the path of the emergent ray at point P and rotated about an axis passing through the centre and perpendicular to the plane of the polaroid a For a particular orientation there shall be darkness as observed through the polaoid b The intensity of light as seen through the polaroid shall be independent of the rotation c The intensity of light as seen through the Polaroid shall go through a minimum but not zero for two orientations of the polaroid d The intensity of light as seen through the polaroid shall go through a minimum for four orientations of the polaroid
