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 545 nm light from a mercury-vapor lamp. interference fringes are formed, with 20.0 fringes per centimeter. find the angle of the wedge?

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
