What is Visible light?

Visible light is the part of sunlight we can see with our eyes.

Imagine you're playing with a flashlight in a dark room. When you turn it on, you can see everything around you, your toys, your walls, even your shadow! That’s because the flashlight sends out light, and your eyes catch it and send the message to your brain, so you know what's there.

What Makes Light Visible?

Visible light is like a rainbow made of different colors. You might have seen a rainbow after the rain, red, orange, yellow, green, blue, indigo, and violet. Each color has its own wavelength, which is like how long each part of the rainbow is. Your eyes can see these colors because they're just the right size for your brain to understand.

How We Use Visible Light

You use visible light every day, when you read a book, look at a picture, or even smile in front of a mirror. It’s like having a special friend who helps you know what's around you, all day long!
