Question

State Snell's law refraction

Answer 1

Answer:

Snell's Law states that the ratio of the angle of incidence to the angle of refraction of a wave as it travels through a boundary between two media is a constant termed the refractive index.

Answer 2

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.
