Document Summary
Chapter 36 diffraction: when waves encounter an edge, obstacle, or aperture the size of which is comparable to the wavelength of the waves, the waves diffract or spread out (diffraction pattern) as they travel and undergo interference. 36-2 intensity in single-slit diffraction: the intensity of the diffraction pattern of a single-slit diffraction at any given angle is given by: represents the intensity at the center of the pattern. 36-4 diffraction by a double slit: diffraction by two slits produce a combined double-slit interference and diffraction by each is expressed as the slits are the pattern identical, slit. 36-6 gratings: dispersion and resolving power: the spreading of waves and diffraction lines by wavelength created by diffraction gratings is referred to as dispersion most accurately, dispersion is the measure of the angular separation ( ) of the line it produces for the differing wavelengths (
