Rainbows are one of nature’s most mesmerizing sights, but they’re not actual objects—they’re illusions created by light refraction.
When sunlight passes through raindrops, it bends, splits, and reflects, forming a spectrum of colors. The angle at which light is refracted determines the arc shape, while the colors appear due to different wavelengths of light.
Interestingly, rainbows are actually full circles, but we usually see only half from the ground. Pilots and mountaineers sometimes witness complete, circular rainbows from above!
