Formation of a Rainbow: A Detailed Explanation

A rainbow is one of nature’s most breathtaking phenomena, created through the interplay of sunlight and raindrops. Here’s a detailed breakdown of the process:

Sunlight Composition:
Sunlight is composed of seven colors—Violet, Indigo, Blue, Green, Yellow, Orange, and Red (VIBGYOR). These colors combine to appear white to the naked eye.

Refraction:
As sunlight enters a raindrop, it slows down and bends. This bending of light is called refraction. Since each color in the spectrum bends by a slightly different amount, the light begins to disperse into its constituent colors.

Internal Reflection:
After refraction, the light travels inside the raindrop and hits the inner surface. Here, it undergoes total internal reflection, where the light bounces back inside the drop rather than passing through.

Second Refraction (Emergence):
The reflected light exits the raindrop, bending again as it leaves. This second refraction further separates the colors, making them more distinct.

Formation of the Rainbow Arc:
Millions of raindrops work together to form the rainbow. Each raindrop contributes to a single color visible to your eyes. The red light appears at the top of the arc because it bends the least, while violet appears at the bottom due to its higher bending angle.

Observer’s Perspective:
A rainbow is always seen opposite the sun. Its circular shape forms due to the consistent angle of 42 degrees (approx.) between the sunlight and the observer’s line of sight. However, the ground typically obstructs the bottom half, making it appear as a semi-circle.
