79 - How does a rainbow form after it rains?

A rainbow forms after it rains when sunlight passes through the tiny drops of water in the air. This creates a big, colorful bow in the sky. Here's how it happens:

1. The sun shines through the water drops.
2. The light bends and separates into different colors, like a prism.
3. The colors spread out and form a big, colorful arc shape, which is the rainbow.
4. The colors always appear in the same order: red, orange, yellow, green, blue, indigo, and violet.

So, after a rain, when the sun comes out, the water drops in the air create a beautiful rainbow just for you to see.
