Interference was observed in interference chamber when air is present. Now the chamber is evacuated and if the same light is used, then for the same arrangement. |
No interference pattern will be obtained.

The fringe width is slightly increased. |
Since refractive index of air is slightly greater than 1 so fringe width will increase when air is replaced by vacuum. |
