Question

state and explain senells 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

Answer:

Snell's law is especially important for optical devices, such as fiber optics .

Snell's law states that the ratio of the sine of the angles of incidence and transmission is equal to the ratio of refractive index of the materials at the interface.
