Question 1

In an air wedge formed by two plane glass plates touching each other along one edge there are 4001 dark lines observed when viewed by reflected monochromatic light. When the air between the plates is evacuated, only 4000 such lines are observed. Calculate the index of refraction of the air from this data.

Question 2

If mth dark fringe appears at a distance x from the edge then

x = mλ/(2nθ)

In the present problem we have
