Question

Explain the laws of refraction
(Snell's Law)​

Answer 1

Answer:

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

• The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane.

• The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.
