A Ray of Light Traveling in Air Makes a 63

question 69

Short Answer

A ray of light traveling in air makes a 63.0° angle with respect to the normal of the surface of a liquid. It travels in the liquid at a 39.2° angle with respect to the normal. Find the critical angle for total internal reflection for this interface.
