What is the index of refraction of the gas

Reference no: EM13559905

One leg of a Michelson interferometer contains an evacuatedcylinder of lenght L, having glass plates on each end. A gas isslowly leaked into the cylinder until a pressure of 1 atm isreached. If N bright fringes pass on the screen when light ofwavelength λ is used, what is the index of refraction of the gas?
