flat. When two crests meet, they produce one, bigger crest. When two troughs
collide, they make a single, deeper trough. Believe it or not, you\\\\\\\'ve just
found a key to understanding how a hologram works. But what do waves in a
pond have to do with those amazing three-dimensional pictures? How do
waves make a hologram look like the real thing?

It all starts with light. Without it, you can\\\\\\\'t see. And much like the
ripples in a pond, light travels in waves. When you look at, say, an apple,
