how would you do this one...
-
how would you know what exists in the emission spectra and not in the absorption spectra
-
Well, when a photon is absorbed, the atom is excited from ground state. However when a photon is emitted, the electron can return to ground state in multiple levels.
So an energy level that exists in the emission spectrum but not in the absorption spectrum is when the electron falls from n=3 to n=2 (not possible with absorption)

Thats the bit i dont get in vcaa 09 electron is excited from the first excitation state.

so if there were more than the 3 levels say up to 8, n=8 to n=7, n=6 to n=5 etc would also be examples of that?
