Homework Help: physics

Posted by Jason on Monday, March 29, 2010 at 8:31pm.

Two flat slides of glass are seperated at one edge by a thin wire, as shown below. The top surface of the upper slide and the bottom surface of the lower slide have special coatings on them so that they reflect no light. The system is illuminated with light of wavelength 550 nm. Looking down from above you see 40 interference minima. What is the diameter of the wire? Assume that the last minima occurs at the right edge where the wire is placed.
