Michael Patino 01115539 Chem 1122-Trupta Experiment 8- Atomic Spectroscopy Objective/Aim of the Lab- The objective of this experiment was involve spectroscopic methods to explore the light emitted by several different atomic sources including mercury, hydrogen and a number of metal atoms (Lithium, Sodium, Potassium, Calcium, Strontium and Barium) heated in a flame. Furthermore, this experiment provides an introduction to the relationship between atomic line spectra and atomic structure. Introduction/Background Information- The perception of color by our eyes is due to our ability to distinguish wavelengths of light in a very small region of the electromagnetic spectrum referred to as the visible region. This region widens from about 400 nm to 750 nm. Light that contains wavelengths from the entire range of visible radiation appears to our vision as white. We associated the white objects with a higher temperature than those that appear red. In addition, this lead to Planck’s black body radiation law which links the distribution of
