Total internal reflection is the reflection of electromagnetic radiation from the interface of medium with larger index of refraction with a medium of smaller index of refraction when making an angle to the normal. Total internal reflection can be used to losslessly redirect a light beam in the direction of its source using a 45°-45°-90° prism.
