Brewster's Angle

Brewster's angle is the specific angle at which light with a particular polarization is perfectly transmitted through a surface, like a glass lens, without any reflection. When light hits a surface at this angle, the reflected light is completely polarized, meaning its waves vibrate in one direction. This phenomenon is named after the Scottish physicist Sir David Brewster. It is significant in optics and is often used in photography and laser applications to reduce glare and enhance image quality. Understanding this concept helps in manipulating light in various technological fields.
