Question

what are rules of refraction???????????​

Answer 1

Answer:

Snell's law 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, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane.

*The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant.
