Snell's Law

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 and glass.

This lesson will discuss the speed that light travels and how it relates to any other medium. This lesson will show and explain how to find the speed of light in water. When light refracts it follows the law of refraction which will be shown and explained. A diagram will be drawn to better understand the concept.
