comment Why are electromagnetic waves not able to pass through a hole with a diameter smaller than the wavelength?
Oh come on. If you merge the two holes into one, the diameter becomes squrt(2). And the power is 4 times: that is, diameter to the fourth. Like I said in the first place. For a correct explanation of the exponent, re-read what I wrote in my answer.

comment How does a Wavefunction collapse?
Let's remember your starting position. Here is what you said: "You can measure the energy eigenstate of a hydrogen atom by measuring the magnetic moment of the atom, which will depend on the angular momentum of the electronic state, the energy of the electron, and the alignment of the electron's spin."

Oh come on. They both have zero orbital energy. And dont' try to squirm out of it by invoking the fine structure constant.

@jerrySchirmer no you can't measure the energy of a hydrogen atom by measuring its spin state. The 1s and 2s states have the same spin, so a hydrogen atom with a spin of 1/2 can be in any superposition of the 1s and 2s states.

Anna, downvoting my answer doesn't mean that you're right and I'm wrong.

comment How does a Wavefunction collapse?
The density matrix is related but it's not exactly my territory. I would refer you to this interesting discussion where the people who understand density matrices show that you cannot distinguish between a system where 50% of the atoms are in an excited state versus a system where all the atoms are in a 50-50 superposition of states: physics.stackexchange.com/questions/8049/…

comment How does the hydrogen atom know which frequencies it can emit photons at?
@Lalinsky good answer. You are the only one who is remotely correct on this question. The other answers are all such nonsense.

@JamalS Thanks for doing my latex! I don't know how I'm supposed to be smart enough to do quantum mechanics if I'm too dumb to do latex.

Oh come on now. Does your potassium atom make an audible click when it absorbs a photon from the distant star?
