Two glass microscope slides, of length 10 cm, are in contact at one end and separated by a sheet of paper at the other end, which creates a wedge-shaped film of air. The thickness of the paper is t = 59 μm, and the glass has index of refraction n = 1.5.
Light with wavelength 0.692 μm shines vertically down on the slides. In the resulting interference pattern, what is the distance separating successive dark fringes when viewed from above?
