Experiment 4 Page 3 of 6 Abstract To validate the theory of wave-particle duality and discrete energy levels, excited hydrogen was observed through a spectroscope. The results were discrete lines at 410nm, 432nm, 542nm, and 655nm, not the full spectrum of visible light; this result implies that there are only certain wavelengths of light that can be emitted or discrete energy levels which the electrons can occupy. Plotting the change in energy vs. the inverse of the original energy level squared, the slope is found to be equal to Rydberg’s constant, validating the Schrodinger energy equation. All of the data confirms that there are discrete energy levels for electrons in the atom and that movement between energy levels requires specific wavelengths of light, also validating the theory of wave-particle duality of matter. In troduction In this experiment, the theory of the wave-particle nature of matter and the equations associated with it were examined and tested for evidence. According to this theory and the equations, such as the Schrodinger equation, electrons move in discrete orbits around the nucleus with discrete energies. This theory came from Einstein’s explanation of the photoelectric effect, in which only certain wavelengths of light could
