Q: One form of this phenomenon can be modeled by the Cornu Spiral, a parametric plot of two integrals of arc length. The Rayleigh Criterion limits the resolution of images produced by this phenomenon when light goes through a circular (*) aperture. Airy Disks and Newton's Rings are patterns formed by light undergoing this phenomenon, which has near-field and far-field types named for, respectively, Fresnel (fruh-NELL) and Fraunhofer (FRAUN-hoff-er). For 10 points, name this phenomenon in which light bends upon encountering a small obstacle.
