Lab: Spectra of Gases

Yesterday we learned that each element emits only certain frequencies of photons. Today we used that idea to identify two unknown gases. In this lab we observed ten different gases through a spectroscope an drew their spectras. I gave you the spectra of two unknown gases. Your job is to compare the spectra of the unknown gases to those you observed in the lab and identify the unknown gases.

This is due on Monday. To help you out, here is a great page with the emission spectra of all elements.
