Hi @namurphy. Now that #2206 has merged, I am interested in working on this if that is alright. Before I begin, I have two quick questions:

1. Do you think a brief derivation of the dispersion relations should be worked into the notebook? (Maybe something like this)
2. Do you think the "diagrams indicating the nature of each of the waves" should be generated with PlasmaPy/Python or embedded from elsewhere (something like this)?

That would be fantastic! In case you'll be at the APS DPP meeting next week, we'll have a table there if you'd like to stop by.

I think a brief derivation would be helpful. An alternative place would be the docstrings of the classes or module. We wouldn't be able to directly use the Wikipedia text since it is under the copyleft CC-BY-SA license and PlasmaPy is under the permissive BSD 3-clause license, but we could add something similar.

I think it'd be fine to use a graphic from elsewhere, and I like the one you pointed to. I almost mentioned license compatibility here too, but it looks like you're the one who created that figure which is awesome!

Thank you again!

I will definitely stop by!

I think since the derivations of all three DRs are identical, it would be best to add a single derivation to the module docstring if not in the notebook. And I just mean something with similar brevity as the Wikipedia derivation. Although, since I contributed this text to the article, I retain the copyright and can re license if necessary (if my understanding of this is correct).

Thanks. I also just mean something similar. I am unaware of relevant diagrams with compatible licenses, so I just linked my own.
