10 Amazing Scientific Facts You Never Knew About Rainbows
4. Supernumerary Rainbows: The Hidden Bands

Beyond the primary and secondary rainbows, supernumerary rainbows can occasionally be observed. These are faint, pastel-colored bands that appear inside the primary arc. Supernumerary rainbows are a result of wave interference, where light waves overlap and create additional bands of color. The presence of these bands indicates the uniformity of raindrop sizes in a storm. This phenomenon challenges the classical understanding of rainbows, introducing quantum mechanics into the equation. The study of supernumerary rainbows provides insight into the wave-particle duality of light and the subtle nuances of its interaction with matter. These hidden bands are a testament to the complexity and beauty of natural phenomena.
