- A Jamin interferometer is a device for measuring or for comparing the indices of refraction of gases. A beam of monochromatic light is split into two parts, each of which is directed along the axis of a separate cylindrical tube before being recombined into a single beam that is viewed through a telescope. Suppose we are given the following, • Length of each tube is L = 0.4 m. • λ= 598 nm. Both tubes are initially evacuated, and constructive interference is observed in the center of the field of view. As air is slowly let into one of the tubes, the central field of view changes dark and back to bright a total of 198 times. (a) What is the index of refraction for air?
