What is light?

Light is like the playground that lets us see everything around us.

Imagine you're on a sunny day, and you close your eyes. When you open them again, you can see your toys, your friends, and even the sky! That’s because light is traveling from those things to your eyes, kind of like a message telling your brain what's out there.

Think of light as tiny little messengers called particles, or maybe like waves in a pond. When the sun shines, it sends out these messages, and they travel through the air until they reach our eyes. That’s how we know something is there, even if it's far away!

You don’t just get light from the sun. A flashlight, a lamp, or even your phone screen can send out light too. It's like having a tiny sun in your hand! So, whether you're playing outside or reading in bed, light is helping you see the world, one little message at a time.
