Various Experiments in Laser Interferometry

This document presents a comprehensive overview of various experiments conducted in laser interferometry at Ben Gallup Lab, collaborating with Mike Del Zio. It encompasses detailed setups including general apparatus schematics, index of refraction analysis, and thermal expansion measurements. Key findings include calculated and accepted values for the index of refraction with a 6.62% error, and thermal expansion coefficients demonstrating an experimental error of 1.67%. These experimental techniques highlight the fundamentals of constructive and destructive interference, leading to a deeper understanding of optical properties.
