Show, with the help of a diagram, how unpolarised sunlight gets polarised due to scattering.

उत्तर
Unpolarized light scattering from air molecules shakes their electrons perpendicular to the direction of the original ray. The scattered light therefore has a polarisation perpendicular to the original direction and none parallel to the original direction.
