Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...
