The optic axes of two polaroids are inclined at an angle of `45^(@)` with other, Unpolarised light of intensity `I_(0)` being incident on the first polaroid emerges from the second polaroid. Find the intensity of the emergent light.

The optic axis of two polaroids are inclined at an angle of 45^(@) with each other. Unpolarised light of intensity I_(0) being incident on the first polaroid emerges from the second polaroid. Find the intensity of the emergent light.

The optic axes of two polaroids are inclined at an angle of 45@ with each other. Unpolarised light of intensity I_0 being incident on the first polaroid emerges from the second polaroid. Find the intesity of the emergent light.

A polaroid is inclined at an angle 45^(@) with the incident light of intensity I_(0) . After polarisation, intensity of the light emitted from the polaroid is

Two polaroids P_(1) and P(2) are placed with pass axes perpendicular to each other. Unpolarised light of intensity I_(0) is incident on P_(1) . A thrid polaroid P_(3) is kept in between P_(1) and P_(2) such that its pass axis makes an angle of 45^(@) with that of P_(1) . Determine the intensity of light transmitted through P_(1) , P_(2) "and" P_(3).

An unpolarised light of intensity I_(0) falls on a pair of Nicol prism. Angle between the two prisms is 60^(@) . Intensity of the light emitted from the prism will be

A narrow beam of unpolarised light of intensity I_(0) is incident on a polaroid P_(1) . The light transmitted by it is then incident on a second polaroid P_(2) with its pass axis making angle 60^(@) relative to the pass axis of P_(1) . Find the intensity of the light transmitted by P_(2) .
