This is something I don't relly get. I keep reading that the intensity of a wave is proportional to the square of its amplitude.
So let's suppose we have a random wave source, with amplitude A0. If we replace that source with five identical copies of it, their collective amplitude is 5A, yes? But have I really raised the energy level at the source by a factor of 25? What am I missing here?
