Brewster’s Angle
Introduction Brewster’s angle, also known as the polarization angle, is a particular angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection. When unpolarized light is incident at this angle, the light that is reflected from the surface is therefore perfectly polarized. Brewster’s Law…

Reflection
Introduction Reflection is a fundamental concept in physics that describes how waves, such as light or sound, bounce off a surface. When these waves encounter a surface, they are reflected back into their original medium rather than being absorbed or transmitted. Law of Reflection The behavior of a wave upon reflection is governed by the…

Refraction
Introduction Refraction is the change in direction of a wave passing from one medium to another caused by its change in speed. This fundamental concept in physics is most commonly observed when a wave, such as light or sound, passes from air into water or from air into glass. The Principle of Refraction When light…

Snell’s Law
Introduction Snell’s Law, also known as the law of refraction, describes the relationship between the angles of incidence and refraction when a wave passes from one medium to another. It is a fundamental concept in the study of optics and wave propagation. Statement of Snell’s Law The law states that the ratio of the sine…
