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

An unpolarised light of intensity 'I_(0)' is passed through the two Polaroid's placed parallel to each other and their transmission. Axes are inclined at an angle 45 . The intensity of the polarised light after passing through the Ploaroid's will be

Two polariods are oriented with their transmision axes making angle of 30^(@) with each other. The fraction of incident un polarised light is transmitted

An unpolarized light with intensity 2I_(0) is passed through a polaroid. The resultant intensity of the transmitted light will be

A beam of unpolarised light of intensity I_0 is passed through a polaroidA and then through another polaroid B which is oriented so that its principal plane makes an angle of 45^circ relative to that of A. The intensity of the emergent light is

An unpolarised light of intensity 32W//m^(2) passes through three polarisers, such that the transmission axis of last polarizer is perpendicular with that of the first. If the intensity of emergent light is 3W//m^(2) then the angle between the transmission axes of the first two polarisers is pi/n radian, where n is____.

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 axes of the first two polarizers ? At what angle will the transmitted intensity be maximum ?

A clear sheet of polaroid is placed on top of a similar sheet so that axews make an angle of sin^(-1) (4/5) with each other. The ratio of intensity of the emergent light to that of polarised light is

An unpolarised beam of intensity I_(0) is incident on a pair of nicols making an angle of 60^(@) with each other. The intensity of light emerging from the pair is
