In the single-slit diffraction experiment of the gure, let the wavelength of the light be 515 nm, the slit width be 6.33 pm, and the viewing screen be at distance D = 3.29 m. Let a y axis extend upward along the viewing screen, with its origin at the center of the diffraction pattern. Also let lp represent the intensity of the diffracted light at point P at y = 16.9 cm. (a) What is the ratio of lp to the intensity lrrl at the center of the pattern? Determine where point P is in the diffraction pattern by giving the orders of nearest (b) maximum (0 is the central maximum) and (cl minimum between which it lies. D Totally destructive interference wave (c) Number Units
