The theory of wave refraction is critically reviewed. The analogy between wave refraction theory and geometrical optics is described. Analytical examples of caustic curves are given, and it is shown that the theory of wave refraction as based upon geometrical optics fails at the caustic and leads to the conclusion that the waves become infinitely high.
