A beam of unpolarised light of intensity is passed through a polaroid A and then through another polaroid B which is oriented so that its principal plane makes an angle of 45^(@) relative to that of A. The intensity of the emergent light

Unpolarised light of intensity I is passed through a polaroid. What is the intensity of emerging polaroised light ?

Unpolarised light of intensity I is passed through a polaroid. What is the intensity of emerging polaroised light ?

A beam of unpolarised light is passed first through tourmaline crystan A and then through another tourmaline crystal B oriented so that its principal plane is parallel to that of A. The intensity of the emergent light is I. If A now rotated by 45^(@) in a plane perpendicular to the direction of the incident ray, the intensity of the emergent light will be

A beam of unpolarised light passes through a tourmaline crystal A and then it passes through a second tourmaline crystal B oriented so that its principal plane is parallel to that of A. The intensity of emergent light is I_(0) . Now B is rotated by 45^(@) about the ray. The emergent light will have intensity

An unpolarized light with intensity 2I_(0) is passed through a polaroid. The resultant intensity of the transmitted light will be
