Measuring the Refractive Index of Glass using a Michelson Interferometer, PHYS 382

There are plenty of descriptions of the measurement of the refractive index of a gas using a Michelson interferometer. But what about a solid? So, I tried measuring the refractive index of a slide of transparent solid material by rotating the sample in a Michelson interferometer. This video describes a little theory, the experiment, and the MATLAB function needed to analyze the results.
