Rainbow Diagram - Simplified Scientific Illustration of Light Refraction #3574228 (License: Personal Use)

This minimalist illustration depicts a rainbow as five evenly spaced concentric arcs over a black background, emphasizing structural symmetry rather than color. The design abstracts the natural phenomenon of light dispersion through water droplets into a geometric form, suitable for diagrams in physics or optics education. The central dark semicircle suggests the shadowed area beneath the primary bow.

Commonly used in educational materials, science textbooks, or digital learning platforms to explain atmospheric optics, refraction, and reflection without color distraction. Matches user intent for conceptual clarity and schematic representation.
