Question

explain about snell's law.................

Answer 1

Snell's law (also known as Snell–Descartes law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.

Answer 2

According to the Snell’s law of Reflection:

* Angle Of Incidence Is Equal To The Angle Of Reflection.

* The Incident Ray, The Reflected Ray and the Normal all lie on the same plane.
