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

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.

Two polaroids are kept with their transmission axes inclined at 30^(@) . Unpolarised light of intensity I falls on the first polaroid. Find out the intensity of light emerging from the second polaroid.

A polaroid is placed at 45^(@) to an incoming light of intensity l_(0) Now, the intensity of light passing through polaroid after polarisation would be

A polaroid is placed at 45^(@) to an incoming light of intensity I_(0) Now, the intensity of light passing through polaroid after polarization would be

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

Two polaroids are kept corssed ("transmission axes at " 90^(@)) to each other. (i) What will be the intensity of the light coming out from the seond polaroid when an unpolarised light of intensity I falls on the first polaroid? (ii) What will be the intensity of light coming out from the second polaroid if a thrid polaroid is kept at 45^(@) inclination to both of them.

Two crossed polaroids are placed in the path of a light beam. In between these a third polaroid is placed whose polarisation axis makes an angle phi with the polarisation axis of the first polaroid Then, intensity of light emerging from the third polaroid, in term of phi is
