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

(a) When an unpolarized light of intensity I_(0) is passed through a polaroid , what is the intensity of the linearly polarized light ? Does it depend on the orintation of the polaroid ? Explain your answer. (b) A plane polarized beam of light is passed through a polaroid . Show graphically the variation of the intensity of the transmitted light with angle of rotation of the polaroid in complete one rotation.

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

A beam of unpolarised light of intensity I_0 is passed through a polaroid 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 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

Unpolarised light of intensity I passes through an ideal polariser A. Another identical polariser B is placed behind A. The intensity of light beyond B is found to be (I)/(2) . Now another identical polariser C is placed between A and B. The intensity beyond B is now found to be (I)/(8) . the angle between polariser A and C is

Two polaroids are placed such that their planes are parallel to each other with their access of transmission at 30°. If an unpolarised light of intensity I_0 is incident on first polaroid polarizer then intensity of light that will be transmitted through the second polaroid is

Unpolarised light of intensity 32 Wm^(-2) passes through three polarisers such that the transmission axis of the last polariser is crossed with first. If the intensity of the emerging light is 3Wm^(-2) , the angle between the axes of the first two polarisers is

When an unpolarized light of intensity I_0 is incident on a polarizing sheet, the intensity of the light which dows not get transmitted is

An unpolarised light of intensity 64 Wm^(-2) passes through three polarisers such that the transmission axis of the last polariser is normal to first. If the intensity of emerging light is 6 Wm(-2),then angle between first two polariser may be

Unpolarized light of intensity 32 Wm^(-3) passes through three polarizers such that the transmission axis of the last polarizer is crossed with the first. If the intensity of the emerging light is 3 Wm^(-2) , what is the angle between the transmission axces of the first two polarizers ? At what angle will the transmitted intensity be maximum ?
