Hi guys, so we currently ran an experiment where we calculated the verdet constant when laser light passed through a glass rod then through an analyzer to a photodetector.
The experiment worked great for us but I wanted to know if anyone has ever calculated the verdet constant for any other substances.

To be more specific, we used equipment bought from TeachSpin,
we used a solenoid with about 1400 turns of copper wires with a power supply hooked up to it at 3 amps to apply a magnetic field of about 11.l(mT/A)I, where I is the current, 3 amps in out case.
The glass rod was specifically called Schott SF-59, and had a verdet constant of about 23 radians/mT*m

has anyone ran the experiment with perhaps a liquid with a known verdet constant? Or any other easy to get substance?
Thanks guys.

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...
