Plotting Graphs for Lab on Line Spectrums and Light Energy Quantum

I'm trying to do my lab homework on line spectrums and plotting graphs, but I'm really confused as to what I should be doing. Is there anyone who actually understands and knows what to do and can help me out with it? I'll be online until midnite at least and someone can email me at silentange13@gmail.com or msn: silentange13@hotmail.com or aim: silentange13.
I'm not 13, its an old screenname, so I actually need some help here with chem and I'd really appreciate if anyone can help me out. Thanks in advance.
