Rainbows happen when sunlight goes through water droplets in the air. Imagine sunlight as a beam of color, white light is actually all the colors mixed together. When it enters a tiny water drop, it slows down and bends, like how a toy car turns when it hits a different surface. Each color bends slightly differently, so they spread out into a spectrum. This makes a rainbow appear in the sky after the rain stops.
Examples
- A child sees a rainbow after a summer shower in the park.
- Water droplets on a window make small rainbows when sunlight hits them.
