The two flat sides of glass are separated at one edge through a thin wire. The top surface of the upper slide and the bottom surface of the lower slide encompass special coating on them so that they reflect no light. The system is illuminated having light of wavelength 548 nm. Looking down from above you see 32 interference minima.

i) Determine the diameter of the wire? Suppose that the last minima take place at the right edge where the wire is positioned.

ii) By submerging the system in a certain liquid we find out that the number of interference minima has raised to 45. Determine the index of refraction of the liquid?
