This was actually a translation, but it is translated correctly. Culminate is the word used in the original, although it doesn't really sound right in this context.
As for the problem, it does make it a lot easier if I don't have to give a number as the answer.
Thanks.
In my problem, it says only this: "The star Arcturus culminates. What is the sidereal time at this moment?"
Do I need to know when the star culminates to solve the problem, and if I do where would I find this information?
I have this problem to solve, but I can't seem to find the right formula. It says to use "an expression for energies of a Bohr atom in a weak magnetic field".
I've looked in my coursebook but I can't find anything useful. Can anyone help me?
I'm studying astronomy and I'm have these problems to solve, but there are a few things I don't really understand, hopefully someone can explain these things to me.
1. Why are spectra of molecules more complex than spectra of atoms? Is it because molecules can be excited in different ways...
Homework Statement
How do you show that in spectra taken along the equator of a rotating rigid sphere the spectral lines are tilted but straight?
Homework Equations
There were no equations given in the problem, so I guess you can use whatever equations you know.
