We have atom of sodium (z 11), find: (a) what is the electron configuration of sodium in its ground state? in its first excited state? (b) give the spectroscopie notation s l) for each of these states in the ls coupling approximation. (c) what are the sodium "d-lines" and why do they form a doublet?

b.

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

wavelength divides in half and speed stays the same.
