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

The axes of a polarizer and an analyzer are oriented at 30^(@) to each other. (a) If unpolarized light of intensity I_(0) is incident on them, what is the intensity of the transmitted light? (b) Polarized light of intensity I_(0) is incident on this polarizer-analyzer system. If the amplitude of the light makes an angle of 30^(@) with the axis of the polarizer, what is the intensity of the transmitted light?

Unpolarised light of intensity I is passed through a polaroid. What is the intensity of emerging polaroised light ?

The axes of a polarizer and an analyzer are oriented at right angles to each other. A third Polaroid sheet is placed between them with its axis at 45^(@) to the axes of the polarizer and analyzer. (a) If unpolarized light of intensity I_(0) is incident on this system, what is the intensity of the transmitted light? (b) What is the intensity of the transmitted light when the middle Polaroid sheet is removed?
