Objectives

The hydrogen atom has only one orbital electron surrounding a nucleus consisting of a single proton, this is why it serves as a good model system to study energy levels of an atom. In this experiment you will apply spectroscopy techniques to study the hydrogen atom. Specifically you will:

  1. Obtain a spectrum of the Balmer series of hydrogen atom and determine the Rydberg constant.
  2. Observe the isotopic shifts of hydrogen and deuterium and calculate the mass ratio of deuterium and proton.
  3. Learn the basic principles of spectroscopic experimental equipment.
