SUMMARY
The discussion centers on calculating the displacement required for the movable mirror of a Michelson interferometer to produce 2000 fringes using a 589-nm light source. The key equation involves the relationship between the wavelength and the path length difference, where constructive interference occurs at integer multiples of the wavelength. Specifically, to achieve 2000 fringes, the path length difference must equal 2000 times the wavelength, resulting in a total displacement of 2000 * 589 nm, or 1.178 mm. Additionally, a question regarding the Sagnac interferometer's configuration and intensity reduction is raised, indicating a need for further analysis of light behavior in that setup.
