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 an angle of `60^(@)` to the pass axis of `P_(1)`. Find intensity of light transmitted by `P_(2)`.

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) .

(a) Distinguish between unpolarized light and linearly polarized light. How does one get linearly polarised light with the help of a plaroid ? (b) A narrow beam of unpolarised light of intensity I_(0) is incident on a polaroid P_(1) .

Unpolarised light of intensity I is incidnet of the polaroid. What will be the intensity of light transmitted by the polaroid?

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).
