Question

State shells law of refraction

Answer 1

In optics, the law is used in ray tracing to compute the angles of incidence or refraction, and in experimental optics to find the refractive index of a material. The law is also satisfied in metamaterials, which allow light to be bent "backward" at a negative angle of refraction with a negative refractive index.

Snell's law is used to determine the direction of light rays through refractive media with varying indices of refraction. The indices of refraction of the media

Answer 2

ur question is wrong dear it is Snell's law of refraction which states that -----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 andrefraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.
