Abstract
A comparison of the index of refraction of two lasers as refracted through the same media will result in the dispersion. By using the Michelson Interferometer experiment to find the wavelengths of various lasers and a semi-cylindrical prism to calculate the indices, the different of the two indices can be taken to get the dispersion of the two different wavelengths from the lasers. The calculated dispersion was 0.014 \(\pm\) 0.13. This dispersion is consistent with what would be expected from only two separate lasers that were not many wavelengths apart. Given more options for laser colors to analyze, the data would be a lot more accurate.
