Brewster Law ?
3marks 12th​

Answer 1

Brewster's law, relationship for light waves stating that the maximum polarization (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.

Answer 2

The law is named after a Scottish physicist, Sir David Brewster, who first proposed it in 1811. ... The figure shows a ray of ordinary (nonpolarized) light of a given wavelength incident on a reflecting surface of a transparent medium (e.g., water or glass).
