42. In order to measure the refractive index of ammonia in one arm of a Michelson interferometer placed on both sides of the closed evacuated to a high vacuum glass cell length l = 15 cm. When filling cuvette ammonia interference pattern for the wavelength λ = 589 nm shifted to 192 bars. To determine the refractive index n1 of ammonia.
