Brewster’s Law: In 1811 Brewster’s proposed it . When   Un-polarized   light is incident at the angle called Brewster’s angle or angle of polarization , the light that is reflected from the surface is therefore perfectly polarized . He was able to prove that the tangent of the angle of polarization is numerically equal to the refractive index of the medium. That is....

Polarization:   Polarization   is a property of waves   that describes the orientation of their   oscillations. If a wave oriented to a single direction is called polarization. We can get Polarized Light form Un Polarized light by under way 1.      Repletion 2.      Refraction 3.      Scattering ( বিচ্ছুরন ) 4.      Selective Absorption 5.      Double Polarization
