Introduction[edit | edit source]
Idea[edit | edit source]
We will be constructing an interferometer as a tool for precision measurement. One primary objective is to determine the refractive index of the various gases by analyzing the resulting shift in interference fringes. Additionally, the thermal expansion of the metal sample will be measured by monitoring changes in the optical path length as the temperature of the sample varies. The project will highlight the relationship between wave optics and measurable physical parameters and illustrates the advantages of high-precision experimental technique.
