Four polaroids are placed such that the optic axis of each is inclined at an angle of `30^(@)` with the optic axis of the preceding one. If unpolarised light of intensity I_(0) falls on the first polaroid, the light transmitted from the fourth 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.

An unpolarised beam of intensity I_(0) falls on a polaroid . The intensity of the emergent light is

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.

Three polaroids are placed insuch a manner that the third polaroid is crossed with the first.When a beam of unpolarised light of intenstiy 24 W m^(-2) falls on the first polaroid,the intensity of light reduces to 3W m^(-2) on emerging fromo the thrid polariod.Find the angle between the trnasmission axes of the second and third polaroid.

Two polaroids are placed such that their planes are parallel to each other with their access of transmission at 30°. If an unpolarised light of intensity I_0 is incident on first polaroid polarizer then intensity of light that will be transmitted through the second polaroid is

Two polaroids are placed such that their planes are parallel to each other with their access of transmission at 30°. If an unpolarised light of intensity I_0 is incident on first polaroid polarizer then intensity of light that will be transmitted through the second polaroid is

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

Two polaroids are crossed. If one of them is rotated through 30^(@) and unpolarised light of intensity l_(0) is incident on the first polaroid, then the intensity of transmitted light will be

Two polaroids are crossed. If now one of them is rotated through 30^(@) and unpolarised light of intensity l_(0) is incident on the first polaroid, then the intensity of transmitted light will be
