Two curves are shown - the excitation spectra and the emission spectra as well as the stokes shift (the difference in nanometers between the peak amplitudes of both curves). From looking at the graph, the peak amplitude of the excitation spectrum is around 450...
We will make qualitative observations of the emission spectra, or pattern of wavelengths (atomic spectra), emitted by five different elements in this lab. While we will not be looking the full spectra produced, the color that we can see with our naked eye can help us to identify the wavelength of light produced.

Introduction to the Flame Test Lab: The Flame Test lab was an in-class lab where we tested chemicals in the flames to see the wide range of colors in the color spectrum. The secondary purpose of the lab was to identify unknown compounds that we would test and then guess as to what they were. The Flame Test lab was done in several parts.
In Figure 12.8 you can see the line emission spectrum of hydrogen. Figure 12.9 shows the absorption spectrum. It is the exact opposite of the emission spectrum!

Nov 29, 2007 · Thalium is another but I don't think you will see that in a school lab. In principle there's no reason why non-metals cant be identified by a flame test. The blue colour of a bunsen flame is due to a bunch of non-metals (excited CO molecules iirc) emiting light. However, it happens that none of the non metals emits much light in the visible region.
