A wedge-shaped film of air is made by placing a small slip of paper between the edges

Question:

A wedge-shaped film of air is made by placing a small slip of paper between the edges of two flat plates of glass. Light of wavelength 700 nm is incident normally on the glass plates, and interference bands are observed by reflection.

(a) Is the first band near the point of contact of the plates dark or bright? Why?

(b) If there are five dark bands per centimeter, what is the angle of the wedge?
