Unpolarised light of intensity I_0 is passed through a polaroid A, and intensity of light after passing polaroid A becomes I_1 . Light emerging from polaroid A is passed through another polaroid B, whose axis is inclined at an angle 60^@ with the axis of A. Intensity of light after emerging from B becomes I_2 .
An unpolarized light with intensity 2I_(0) is passed through a polaroid. The resultant intensity of the transmitted light will be
Unpolarised light of intensity I is incidnet of the polaroid. What will be the intensity of light transmitted by the polaroid?
A beam of unpolarised light of intensity I_0 is passed through a polaroidA and then through another polaroid B which is oriented so that its principal plane makes an angle of 45^circ relative to that of A. The intensity of the emergent light is
Two polaroids are crossed. If one of them is rotated through 30^(@) and unpolarised light of intensity l_(0) is incident on the first polaroid, then the intensity of transmitted light will be
Two polaroids are crossed. If now one of them is rotated through 30^(@) and unpolarised light of intensity l_(0) is incident on the first polaroid, then the intensity of transmitted light will be
An unpolarised beam of intensity I_(0) falls on a polariod. The intensity of the emergent light is :
