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. Interference fringes are formed, with 15.0 fringes per centimeter. Find the angle of the wedge. 0.0234° 0.0104° 0.234° 0.0468°

Step 1
We have two glass plates forming a thin wedge with air between them. When illuminated by light of wavelength 546 nm, interference fringes are observed. The number of fringes per unit length (centimeter) is given as 15.0 fringes/cm. We need to find the angle of the Show more…

35.29. 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.
A wedge-shaped film of air is made by placing a small slip of paper between the edges of two flat pieces of glass. Light of wavelength 500 nm is incident normally on the glass, and interference fringes are observed by reflection. If the angle made by the plates is 0.017°, find the spacing between consecutive dark fringes.
