Two circularly shaped linear polarisers are placed coaxially. The transmission axis of the first polarizer is at `30^(@)` from the vertical while the second one is at `60^(@)`, both in the clockwise sense. If an unpolarised beam of light of intensity `I = 20 W//m^(2)` is incident on this pair of polarisers, then the intensities `I_(1)` and `I_(2)` transmitted by the first and the second polarisers, respectively, will be close to

Three circularly shaped linear polarisers are placed coaxially. The transmission axis of the first polariser is at 30^(@) , the second one is at 60^(@) and the third at 90^(@) to the vertical all in the clockwise sense. Each polariser additionally absorbs 10% of the light. If a vertically polarised beam of light of intensity I = 100 W//m^(2) is incident on this assembly of polarisers, then the final intensity of the transmitted light will be close to

If unpolarised light of intensity I_(0) is incident on the polarising plate, intensity of emerging light will be ......

When an unpolarised light intensity I_0 is incident on a polarising sheet ,the intensity of the light which does not get transmitted 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
