it is the relationship for light waves stating that the maximum polarization or vibration in one plane only of a ray of light may be achieved by letting the ray fall on a surface of a transparent medium in such a way that the refracted ray makes an angle of 90° with the reflected ray.
brewster's law derived a relation amongst the polarizing angle ip and the refractive index mu which is well known as Brewster's law. ... When unpolarized light is found to be incident on a transparent medium at any polarizing angle then the transmitted and reflected rays are vertical to each other.
Polarized sunglasses use the principle of Brewster's angle to reduce glare from the sun reflecting off horizontal surfaces such as water or road. In a large range of angles around Brewster's angle, the reflection of p-polarized light is lower than s-polarized light. Thus, if the sun is low in the sky, reflected light is mostly s-polarized. Polarizing sunglasses use a polarizing material such as Polaroid sheets to block horizontally-polarized light, preferentially blocking reflections from horizontal surfaces. The effect is strongest with smooth surfaces such as water, but reflections from roads and the ground are also reduced.
