Question

How is linearly polarised light obtained by scattering zigya

Answer 1

The scattering of light off air molecules produces linearly polarized light in the plane perpendicular to the incident light. The scatterers can be visualized as tiny antennae which radiate perpendicular to their line of oscillation. If the charges in a molecule are oscillating along the y-axis, it will not radiate along the y-axis. Therefore, at 90° away from the beam direction, the scattered light is linearlypolarized. This causes the light which undergoes Rayleigh scattering from the blue sky to be partially polarized.
