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.

Two microscope slides made of glass are illuminated by monochromatic (λ=589nmλ=589nm) light incident perpendicular to the surface. The top slide touches the bottom slide at one end and rests on a thin copper wire at the other end, forming a wedge of air. Dimensions are not to scale. The wire diameter and the thickness of the gap should be very small compared to the thickness of the glass.. If 104 bright fringes appear between the point where the glass slides contact each other and where they contact the wire, what is the minimum diameter D of the wire in micrometers.
Two identical horizontal sheets of glass have a thin film of air of thickness t between them. The glass has refractive index 1.40. The thickness t of the air layer can be varied. Light with wavelength l in air is at normal incidence onto the top of the air film. There is constructive interference between the light reflected at the top and bottom surfaces of the air film when its thickness is 650 nm. For the same wavelength of light the next larger thickness for which there is constructive interference is 910 nm. (a) What is the wavelength l of the light when it is traveling in air? (b) What is the smallest thickness t of the air film for which there is constructive interference for this wavelength of light?
