Total Internal Reflection of Light and Critical Angle of Refraction Physics

This physics video tutorial discusses the total internal reflection of light and how to calculate the critical angle of refraction. Total internal reflection occurs when the incident angle exceeds the critical angle. The critical angle is the angle of incidence when the angle of refraction is equal to 90. Total internal reflections occurs when a light ray travels from a material with a high index of refraction to a material with a low index of refraction. The formula needed to find the critical angle is the equation provided by snell's law. This video includes examples and practice problems relating to the critical angle of water and diamond.
