Two polaroid `A and B` are kept in crossed position. How should a third polaroid `C` be placed between them so that the intensity of polarized light transmitted by polaroid `B` reduces to `(1)/(8)th` of the intensity of unplarised light incident on `A` ?

Two polaroids A and B are kept in crossed position. How should a third polaroid C be placed between them so that the intensityof polarised light transmitted by polaroid B reduces to 1/8 th of the intensity of upolarised light incident on A?

Two polaroids A and B are kept in crossed poisiton.How should a third polariod C be placed between them so that the intensity of polarised ligth transmitted by polaroid B reduces to 1//8th of the intensity of unpolarised light incident on A?

(a) How does an unpolarized light incident on polaroid get polarized ? Describe briefly, with the help of necessary diagram, the polarization of light by reflection from a transparent medium. (b) Two polaroids 'A' and 'B' are kept in crossed position. How should a third polaroid 'C' be placed between them so that the inlensity of polarized light transmitted by polaroid B reduces to 1//8^(th) of the intensity of unpolarized incident on A?

Two polaroids A and B are parallel. How a third Polaroid C be placed between A and B so that the intensity of the emergent light be (A) zero (B) maximum?

Two polaroids A and B are parallel. How a third Polaroid C be placed between A and B so that the intensity of the emergent light be (A) zero (B) maximum?

Two polaroid A and B are set in crossed positions. A third polaroid C is placed between the two making /_theta with the pass axis of first polaroid. Write the expression for intensity of light transmitted from second polaroid. In what orientations will be transmitted intensity be (i) minimum (ii) maximum ?
