4. Consider the Michelson interferometer shown in Fig. 2. In one of the optical branches, there is an air-tight chamber of length d = 4 cm. When the gas is evacuated from the chamber, the interference pattern shifts by 3000 fringes at a wavelength of 620 nm. Determine the index of refraction of the gas inside the chamber. 4.
