Yup another "oh crap I don't have the book" issue. EM Fields, Wangsness

my elements of solid state physics book finally came in the mail but now I need my EM book

If you have it I just need the questions, the book got returned to sender so I need to wait longer for it than expected(I'm not having ANY luck with that this semester)

Anyways, Wangsness' EM Fields, 2nd ed.

1.4, 1.5, 1.6, 1.9, 1.10, 1.13, 1.15, 1.23, 1.24

I've already sent emails to classmates but they suck at checking e-mails sometimes

Hmm, that IS a lot of problems to type out, but I'd appreciate it forrrevverrrrr

Emailing you the problems wouldn't do you any good, they refer to equations in the text by number.

I love Wangsness as a text and if I didn't I would sell it to you. I consider it to be the best text E&M text out there at junior/senior undergrad level.
 
Well unfortunately I'm in a jam 'cuz it's due tomorrow(I expected the book by Friday, got the oops we screwed you email on Friday, and was indisposed alllll Saturday)

if you could just e-mail them I'll try my luck without the pretty numbered equations(the vector and vector calculus and math review of chapter 1 is really similar to what's in my mechanics text's chapter it seems, I could probably figure out what I needed)e-mail's schattenjaeger@verizon.net I'll love you foreverrrrr
 
You're my hero!
 
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...
