comment Regarding Electromagnetic plane wave and Maxwell's equatins
@Insig: I removed the general-relativity tag; this has nothing to do with general relativity; in fact it's not even specifically related to special relativity; it's just electrodynamics and vector calculus.

comment Regarding Electromagnetic plane wave and Maxwell's equatins
@Insig: It doesn't if you link both questions to each other to avoid duplication of efforts.

comment Finding the electric field for a shell of charge
@FrankH: Yes, that's also the one I was referring to; I found it from the FAQ you linked to.

comment Finding the electric field for a shell of charge
@FrankH: I'm sorry, I wasn't aware that you have a different homework policy here; I originally saw this question on math.SE and followed it here when it was migrated. It's rather ironic that the FAQ you linked to (or rather the meta thread that it links to) quotes an obsolete thread on meta.math.SE to argue for this policy, which is not the current math.SE policy on homework (which is basically that everyone deals with it as they see fit).

comment Solving the Schrödinger equation for the double-slit experiment
Note that in most languages that use diacritics (including German), the letters with and without diacritics have only a historical connection and are pronounced quite differently nowadays. Thus leaving off the diacritics is about as bad a misspelling as changing the vowels completely; you might as well have written "Schrudinger". :-) If you can't produce letters with diacritics, you can always copy them from the Web, e.g. from the corresponding Wikipedia articles (which you can find by Googling the names without diacritics :-).

comment 3D Quantum harmonic oscillator
Much as I'd like to answer the question, I think it belongs on physics.SE. The answers are well-known to physicists. See e.g. en.wikipedia.org/wiki/….
