Rainbows are one of nature’s most beautiful phenomena, created by the interaction of light and water droplets in the atmosphere. When sunlight passes through raindrops, it bends (refracts), reflects off the inside surface of the droplet, and then refracts again as it exits. This process separates the white sunlight into its component colors red, orange, yellow, green, blue, indigo, and violet forming a circular arc in the sky. The angle at which the light exits the raindrop determines where each color appears, with red at the top and violet at the bottom.
Rainbows are always seen opposite the sun, and their appearance depends on the observer’s position relative to the raindrops. The best time to see a rainbow is when the sun is low in the sky, such as early morning or late afternoon. Sometimes, a secondary rainbow can appear outside the primary one, caused by double reflection within raindrops, making the colors appear in reverse order. Though rainbows are typically seen after rain, they can also form near waterfalls, fountains, or even in misty conditions, proving that nature has countless ways to showcase its colorful beauty.
