Yes, I know that the now-famous FSU web page uses "redistribution". Do you suppose Hecht, Born and Wolf, and all of the other acknowledged experts would support dumping "reflection"? I would guess the answer is "yes" when the physical reflection coefficient is zero - in order to avoid a logical contradiction. How does a "reflection" occur when the physical reflection coefficient is zero, in violation of the wave reflection model? Why is there often a difference between the physical reflection coefficient and the virtual reflection coefficient? Which one is wrong? The convention that I have adopted is that the word "reflection" is reserved for single wave events. For multiple wave events where interference exists, something besides a simple "reflection" takes place. The intricate color patterns on the surface of a thin film of oil floating on a puddle of water are not simple reflections but instead an interaction of multiple reflected waves. The resulting image bears absolutely no resemblance to the incident image. Following the FSU web page usage, the word "redistribution" is used for multiple wave interaction events like wave cancellation.
