Linearly polarised light is the light wave in which the vibration of electric field vectors are confined in one plane and parallel to one unique direction. The intensity of transmitted light becomes maximum, when the inserted polaroid and analyser (the polaroid which receives light that is transmitted by inserted polaroid) have their axes parallel to each other.
The incident sunlight is unpolarized. Molecule in air acts as a dipole radiator. When the sunlight falls on a molecule, dipole molecule does not scatter energy along the dipole axis; however the electric field vector of light wave vibrates just in one direction perpendicular to the direction of the propagation. The light wave having direction of electric field vector in a plane is said to be linearly polarized.
