Problem 2 (30 points): Consider a Michelson interferometer (see below). A gas cell with a length of 5.0 cm and parallel windows at the ends is placed in one arm. The light has a wavelength of 800 nm in vacuum. When a gas of initial pressure 105 N/m in the cell is being pumped out completely by a vacuum pump, 25 fringes pass by a point on the observation screen. (a) What is the refractive index of the gas? (15 points) (b) What should be the pressure of the gas in the cell to introduce a delay of five full optical periods between light in the two arms of the interferometer? Assume refractive index linearly varies with pressure. (15 points) 5 cm J-1
