Physics 111: Atomic Physics (ATM) Part 1. Balmer Series Physics 111 Advanced Laboratory. Professor Sumner Davis This video accompanies the Atomic Physics Experiment, providing students with an introduction to the theory, apparatus, and procedures for the Balmer Series part of the lab exercise. Atomic spectroscopy was the proving ground for Quantum Mechanics. In this lab you will observe the emission lines of mercury and hydrogen over the range 250 to 750 nm, using a diffraction-grating spectrometer. You will identify and measure the Balmer series of spectral lines in hydrogen, and then use the results to determine the energy levels and the value of the Rydberg constant. Mercury lines are used to calibrate the wavelength scale of the spectrometer. http://advancedlab.org
