Experiments With the Displacement Interferometer

The book Experiments with the Displacement Interferometer by Carl Barus explores the application of the displacement interferometer to various subjects. The author conducts detailed experiments using the interferometer to measure changes in inclination gravitational attraction and refraction of glass columns. The book delves into the challenges faced during the experiments adjustments made for accuracy and the precision of the interferometer in measuring small angles and changes in elongation. It also discusses experiments with film grating Nernst filament and reflection of light from grating surfaces showcasing the versatility and effectiveness of different setups for interferometry experiments.
