in the syllabus it says, "show an undrstanding of the existence of discrete electron energy levels in isolated atoms and deduce how this leads to spectral lines"

are spectral lines produced when an excited electron goes back to its ground state? because it emits photons? is that it?  :-\

"The lines on the spectra are the frequencies of light that exactly match the energy required to make the jumps between energy levels."
right now i'm confused.
are the lines caused by the emission of photons, or the absence of those particular frequencies of light? can someone please explain this?

There is a page on my website. Will post the link when I get home
