| Jan 29, 2017 at 7:54 | comment | added | user | The answer you accepted is not... that correct; for example according to that answer high intensity laser light is "not exactly waves". This might be a better choice. Sometimes the first answer that pops up and looks correct gets most upvotes. Doesn't mean it's the best answer. | |

| Jan 21, 2017 at 11:48 | comment | added | kwah | My initial thought is that a "handwave" doesn't, but having thought about it some more perhaps it does.. Hands colliding cancel each other out/interfere, and a crowd of waving hands is amplified in the sense that it can be seen from a further distance than a single handwave might... Hmm... | |

| Jan 20, 2017 at 10:11 | comment | added | Winther | Related question: How can one tell if a PDE describes wave behaviour?. There are non-linear PDEs that have wave solutions (see e.g. solitons) that don't satisfy the superposition principle. | |

| Jan 20, 2017 at 6:41 | comment | added | Ben S | Well, I would first ask what you mean by wave. The best answer I can think of is whipping out some "wave equation". "If it satisfying this/one of these equations, it is a wave." A lot (not sure if all) the stuff we call waves are linear. But do realize that our classification of waves is arbitrary. | |
