What are light waves?

Light waves are like ripples on a pond, but you can't see them, they're invisible and super fast!

Imagine you're at the beach, and you throw a stone into the water. The water moves in circles around where the stone landed, that’s like a wave. Light works kind of the same way, but instead of water, it uses space to move.

How light waves travel

Light waves are made up of tiny pushes and pulls in energy, just like how your voice makes the air vibrate when you speak. These pushes and pulls can go through things, like when you see a flashlight beam going through a glass of water or even your skin!

What light waves do

When these energy ripples hit something, like your eye or a wall, they make that thing move a little bit, and you see it! That’s how we can see colors, shapes, and everything around us. Without light waves, the world would be dark and quiet.

So even though you can't feel them, light waves are all around you, helping you see the world every day! Light waves are like ripples on a pond, but you can't see them, they're invisible and super fast!
