How Rainbows Form: Refraction, Reflection, and Dispersion of Light • Rainbows occur due to the refraction, internal reflection, and dispersion of light in water droplets. • Sunlight interacts with atmospheric water, usually raindrops, causing the rainbow effect. • The process involves light bending and reflecting within water droplets, resulting in a continuous spectrum of colors. • Rainbows are optical phenomena that can also be observed in mist and spray.
