| Aug 6, 2017 at 16:18 | comment | added | user163104 | @Landau I am a bit confused as to what you mean by mathematical method that allows. I wrote an answer which I deleted because it was too basic and did not address your full question. You have the intuitive (physical) picture, so which part, (and I mean this without offence, seriously ), of the simple extension of the Fourier series idea to wave packets is the problem? Have you checked with MathSE, as you have the physical idea, and MathSE deals with formal derivations and proofs, if that is what you are after? | |
