Of course, in real life when you thump on a solid you do not produce a plane wave; you produce something more like a wave packet. This is not a single phonon mode, but can be expressed as a (linear) combination of them. This is the same as the story for photons; when you turn on a flashlight you're not making plane waves which occupy the entire universe :) | |
