Refraction (3 of 5) What is Total Internal Reflection? An Explanation

Describes the concept of total internal reflection, derives the equation for the critical angle and shows one example. Total internal reflection is the complete reflection of a ray of light that is traveling within one medium, such as water or glass, from the boundary with a second medium back into the first medium. The phenomenon occurs when the angle of incidence is greater than a certain limiting angle, called the critical angle. In general, total internal reflection takes place at the boundary between two transparent media when the ray of light is travel from a medium with a higher index of refraction into a medium with a lower index of refraction.
