Formation of a Hologram

There are several ways of writing down the equation that represents a traveling wave. Some are more precise than others, but you need to know a little mathematics to be able to understand them. On the principle that when you need to explain something you should use the simplest explanation that doesn’t involve cheating, we have chosen one that has nothing more complicated than cosines. If you have done a little trigonometry and can remember that

cosXcosY=12cos(X+Y)+12cos(XY)

that is all ...
