When one studies physics, they study the properties of waves. Especially when looking at acoustics, you'll see there are standing waves, Helmholtz resonators and all sorts of mechanical and acoustic filters. There are electrical resonators and filters too, of course, but my point is that you can see these kinds of properties in all forms of energy transfer.
