Problem 40.6

As shown in Fig. 40-4, two flat glass plates touch along the leftmost edge and are separated at the other end by a spacer. Using vertical viewing and light with λ = 589.0 nm, five dark fringes (indicated by a D in the diagram) are obtained from edge to edge. What is the thickness of the spacer?
