Textbook Question
Chapter 40, Problem 30SP
Two flat glass plates are pressed together at the top edge and separated at the bottom edge by a strip of tinfoil. The air wedge is examined in yellow sodium light (589 nm) reflected normally from its two surfaces, and 42 dark interference fringes are observed. Compute the thickness of the tinfoil.

Two rectangular pieces of plane glass are laid one upon the other on a table. A thin strip of paper is placed between them at one edge so that a very thin wedge of air is formed. The plates are illuminated at normal incidence by 546-nm light from a mercury vapor lamp. Interference fringes are formed, with 15.0 fringes per centimeter. Find the angle of the wedge.
Suppose two flat glass plates 30-cm long are in contact along one end and separated by a
human hair at the other end. If the diameter of the hair is 50µm, find the separation of
the interference fringes when the plates are illuminated by green light, λ = 546 nm.
A double-slit arrangement produces interference fringes for sodium light (l = 589 nm) that are 0.20° apart.What is the angular separation if the arrangement is immersed in water (n = 1.33)?
