Answer 1

it is a formula used to describe a relationship between the angles of incidence and refraction ,when reffering to light or other waves.

Answer 2

Answer:

Like with reflection, refraction also involves the angles that the incident ray and the refracted ray make with the normal to the surface at the point of refraction. This dependence is made explicit in Snell's Law via refractive indices, numbers which are constant for given media1.
