5) You are looking at the fringe pattern on a screen produced by a laser beam passing through a pair of closely-placed slits, and then travelling about a meter until the pattern hits the screen. A) You put a thin sheet of glass over one of the slits (one slit only). The effect of the glass is to add exactly half of a wavelength to the light that passes through that one slit.

One leg of a Michelson interferometer contains an evacuated cylinder of length L, having glass plates on each end. A gas is slowly leaked into the cylinder until a pressure of 1 atm is reached. If N bright fringes pass on the screen during this process when light of wavelength A is used, what is the index of refraction of the gas? Hint: The fringe shifts occur because the wavelength of the light changes inside the gas-filled tube.
