- Nonsense. A wave is something with certain mathematical properties.
- If the values of some measurable something, examined throughout
- space, look like (say) sin(Ar+t) [t=time, r=distance from some point]
- then it is perfectly in order to describe this as a wave travelling
- through space.
-
- To be sure, this is an extension of the use of the term "wave" to describe
- lumps of (say) water wobbling about, or hands waving. So what?
