An unpolarized light is successively throgh two polaroids, each with their transmission axis parallel. If the intensity of unpolarized light be `l_(0)`, then intesity of the light after emerging from second polarizer will be

When unpolarized light is passed through a polarizer , its intensity

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.

An unpolarized light of intensity 25W/m^(2) is passed normally through two polaroids placed parallel to each other with their transmission axes making an angle 37^(@) with each other.Then the intensity of the emerging light is

At what angle should the axes of two polaroids be placed so as to reduce the intensity of incident unpolarized light to 1//3 .

At what angle should the axes of two polaroids be placed so as to reduce the intensity of incident unpolarized light to 1//3 .

Two 'crossed' polaroids A and B are placed in the path of a light-beam. In between these, a third polaroid is C is placed whose polarisation axis makes an angle theta with a polarisation axis of the polaroid A. If the intensity of light emerging from the polaroid a is I_(o) then the intensity of light emerging from polaroid B will be

Unpolarized light of intensity 32 Wm^(-3) passes through three polarizers such that the transmission axis of the last polarizer is crossed with the first. If the intensity of the emerging light is 3 Wm^(-2) , what is the angle between the transmission axces of the first two polarizers ? At what angle will the transmitted intensity be maximum ?
