1. I ´m trying to do the dimensional analysis of the Delta Dirac in 3 Dimensions.

The images you posted aren't showing up on my browser (chromium) - is anyone else having this problem too? You may want to re-post a different way.

This is the Delta Dirac Functin in 3D.

This is my attempt.

The image of your attempt is really really tiny. You might consider reading about how to post equations here using LaTeX. It's a little bit of effort up front, but definitely worth it.

You can read about it here: https://www.physicsforums.com/help/latexhelp/

Oh, and if the itex thing doesn't seem to work, try the double hash mark thing.
 
Thread 'Need help understanding this figure on energy levels'
This figure is from "Introduction to Quantum Mechanics" by Griffiths (3rd edition). It is available to download. It is from page 142. I am hoping the usual people on this site will give me a hand understanding what is going on in the figure. After the equation (4.50) it says "It is customary to introduce the principal quantum number, ##n##, which simply orders the allowed energies, starting with 1 for the ground state. (see the figure)" I still don't understand the figure :( Here is...
Thread 'Understanding how to "tack on" the time wiggle factor'
The last problem I posted on QM made it into advanced homework help, that is why I am putting it here. I am sorry for any hassle imposed on the moderators by myself. Part (a) is quite easy. We get $$\sigma_1 = 2\lambda, \mathbf{v}_1 = \begin{pmatrix} 0 \\ 0 \\ 1 \end{pmatrix} \sigma_2 = \lambda, \mathbf{v}_2 = \begin{pmatrix} 1/\sqrt{2} \\ 1/\sqrt{2} \\ 0 \end{pmatrix} \sigma_3 = -\lambda, \mathbf{v}_3 = \begin{pmatrix} 1/\sqrt{2} \\ -1/\sqrt{2} \\ 0 \end{pmatrix} $$ There are two ways...
