Wave Interference in Uniform Raindrops Generates Multiple Supernumerary Rainbow Arcs
What Was Observed (Empirical Data)
A sequence of at least five supernumerary rainbow bands was captured via ground-based digital photography inside a primary rainbow over the New Jersey coast. The image documents alternating pastel green and purple interference fringes generated by constructive and destructive interference of sunlight. The visibility of multiple sharp fringes indicates light scattering through an unusually uniform distribution of water droplets with diameters smaller than one millimeter.
The Reality Check (Anti-Hype Analysis)
This observation does not represent a bizarre atmospheric anomaly or an unmapped meteorological phenomenon, but established wave optics modeled by Thomas Young and George Biddell Airy in the nineteenth century. These delicate interference arcs do not survive typical precipitation conditions, as slight variations in raindrop radii quickly wash out the interference pattern. In addition, single-frame ground photography serves as an opportunistic visual record rather than a direct, instrumented microphysical aerosol measurement.
