Determine the angle of the wedge

Reference no: EM13278426

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 542nm light from a mercury-vapor lamp. Interference fringes are formed, with 14.0fringes/centimeter .

Find the angle of the wedge.
