Sidebar 9.SB2: Interference Patterns in Caustics
The bright sharp-edged triangle is a caustic, that is a line of focused light. The oscillating intensity of the interference fringes across the caustic is described by the Airy function.

§36.14(i) Caustics
The physical manifestations of bifurcation sets are caustics. …Diffraction catastrophes describe the (linear) wave amplitudes that smooth the geometrical caustic singularities and decorate them with interference patterns. …

§9.16 Physical Applications
 Airy on the intensity of light in the neighborhood of a caustic (Airy (1838, 1849)). …
