How does a rainbow form?

Have you ever seen the colorful arc in the sky after a rainstorm? That is called a rainbow! A rainbow is both enchanting and a wonderful demonstration of science. But how does it form?

A rainbow forms when sunlight enters raindrops, refracts, reflects inside them, and refracts again as it exits. Sunlight is actually white but contains many colors ranging from red to violet. When this light enters a raindrop, it first refracts (changes direction), then reflects inside the drop, and refracts again as it leaves. During this process, the light creates a colorful arc across the sky.

To see a rainbow, the Sun must be behind you and the rain must be in front of you. Rainbows typically appear in the morning or late afternoon. The most common rainbow displays seven colors: red, orange, yellow, green, blue, indigo and violet.
