A type of rainbow that appears in fog or mist, typically appearing as a white arc due to water droplets being too small to refract light into colors.
From 'fog' + 'bow' (an arch or curved shape). This is a descriptive compound created by naturalists to name this optical phenomenon; it mirrors the structure of 'rainbow.'
A fogbow is like nature's ghost rainbow—it's caused by the same physics as a regular rainbow but the tiny water droplets in fog scatter all colors equally, canceling them out and leaving just white, which is both scientifically fascinating and eerie.
