Problem: A 12 cm radius sphere of glass (n = 1.33) is cut in half and placed convex-side down on a table. A light of wavelength 500 nm is shown on the flat surface of the glass from directly above, producing an interference pattern. What is the radius of the first bright spot in the pattern? Will this interference pattern be seen across the entire glass surface?
