Question

5. Measuring the refractive Index of a gas M2 2 cm M1 To vacuum pump In one arm of a Michelson interferometer, a glass chamber is placed with attachments for evacuating the inside and putting gases in it. The space inside the container is 2 cm wide. Initially, the container is empty. As gas is slowly let into the chamber, you observe that dark fringes move past a reference line in the field of observation. By the time the chamber is filled to the desired pressure, you have counted 122 fringes move past the reference line. The wavelength of the light used is 632.8 nm. What is the refractive index of this gas?

In one arm of a Michelson interferometer, a glass chamber is placed with attachments for evacuating
the inside and putting gases in it. The space inside the container is 2 cm wide. Initially, the container is
empty. As gas is slowly let into the chamber, you observe that dark fringes move past a reference line in
the field of observation. By the time the chamber is filled to the desired pressure, you have counted 122
fringes move past the reference line. The wavelength of the light used is 632.8 nm. What is the
refractive index of this gas?
