Refraction of Light
Snell's Law: Used to determine the direction of light rays through refractive media with varying indices of refraction. The indices of refraction of the media are used to represent the factor by which a light ray's speed decreases when traveling through a refractive medium, such as glass or water, as opposed to its velocity in a vacuum.
