Answer 2

Explanation:

A change of direction that light undergoes when it enters a medium with a different density from the one through which it has been traveling – for example, when, after moving through air, it passes through a prism . 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
