The Brewster angle is the angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface without any reflection. This occurs when the refracted and reflected rays are perpendicular to each other, and it is used in applications like anti-reflective coatings and polarized sunglasses.

The angle of incidence is the angle between an incoming wave or ray and the perpendicular to the surface it encounters. It plays a crucial role in determining how waves, such as light or sound, are reflected or refracted at interfaces between different media.

Anti-reflective coatings are thin film layers applied to surfaces, such as lenses and screens, to reduce unwanted reflections and increase light transmission. These coatings enhance visual clarity and efficiency by minimizing glare and improving contrast in optical devices.
