We have the initial orbital angular momentum state in the x basis as |l,ml>x=|1,1>x. We are asked to find the column vector in the z-basis that represents the initial orbital angular momentum of the above state. It then says "hint: use an eigenvalue equation".
This is just a qualitative question that is along side my main lecture with Griffiths EM book.
Basically we have a very long cylinder with charge density sigma and radius a along the z axis. This is mostly beside the point and is just to setup the question. The question...
Important: All Logs are base 10 and not the natural log.
This question is from Foundations of Astrophysics from chapter 19
Suppose the Milky Way consisted of 2.7x10^11 stars, each of solar luminosity MB=4.7. What would be the absolute magnitude of the whole galaxy?
