Light can be colorful, just like how crayons come in many shades!
Imagine you have a big box of colored pencils, each one is a different color. Now think of light as being made up of lots of tiny, invisible pencils, all mixed together. When they’re all mixed, the light looks white, like a bright sunny day. But when you separate them, you can see all the individual colors, red, blue, green, and more!
How We See Colors
When light goes through something like a prism (a clear triangle shape), it bends and splits into its different colors, just like how a rainbow appears after rain. This is because each color moves at a slightly different speed when it passes through the prism.
You can also see this in real life, think of a CD or DVD. When you tilt it under light, you’ll see pretty colors all over it, just like magic! But it’s really just light being split into its colorful parts.
So, colors of light are like the different shades in your crayon box, they’re all hiding inside white light, waiting to be seen!
Examples
- When you see red, blue, and green on a TV screen, it's because of the colors of light mixing together.
