Round 8: Tossup 5

This process is caused by devices partially named “echelle,” which have relatively few lines per millimeter. Either prisms or devices named for this process are used as dispersive elements (10[1])in spectrometers. The first zero of the Bessel function J-sub-one equals the constant 1.22 in Rayleigh’s criterion for resolution limited by this process. (10[1])This process’ (10[1])intensity maxima occur when sine theta is proportional to an integer multiple of wavelength by Bragg’s Law. Tightly spaced slits make up gratings named for (10[1])this process, which light undergoes before self-interfering (10[1])in the double slit experiment. For 10 points, name this process in which light bends (10[1])around an object. ■END■ (10[1])
