What are Sound and Light? 🤔
**Energy** is what makes things happen! **Sound** and **light** are two different kinds of energy. They both travel in **waves**, but they are very different.
**Light energy** is what helps us see. It travels super, super fast! We can see light from the Sun, a light bulb, or a firefly. Light doesn't need to travel through anything to get to us.
**Sound energy** is what we hear. It is made when something vibrates. Sound waves need to travel through a medium like air, water, or a solid to reach our ears. You can't hear anything in outer space because there's no air!
