What They (Probably) Don't Teach You About Rainbows At School?

Rainbows are like a colorful puzzle that happens when light plays hide-and-seek with water droplets in the air.

Imagine you're outside after a rainstorm, and the sun comes out, that’s when the fun begins! Light from the sun goes into each water droplet, like a tiny ball. Inside the droplet, the light bounces around like it's playing tag. When it finally leaves the droplet, it changes direction, kind of like how a ball might roll off a slope.

Now, here’s the twist: different colors inside the light bend at slightly different angles when they leave the droplet. That’s why you see red on one side and violet on the other, each color has its own special path.

So when lots of water droplets do this same trick all together, it makes a big, pretty rainbow in the sky!

Why You Don’t See It Every Time

Rainbows only show up if you’re standing in just the right spot, like between the sun and the rain. If you move too far away or the sun moves, your rainbow might disappear, like a disappearing act!

Examples

  1. A rainbow forms when sunlight passes through raindrops, bending the light into different colors.
  2. Sometimes you see double rainbows because the light reflects twice inside the raindrop.
  3. You might not always see a full rainbow, it depends on where you are and the angle of the sun.
