What are sound waves?

Sound waves are special waves that we can't see but we can definitely hear! To understand sound waves, first, you should know that sound is created when something vibrates or moves back and forth really fast.

These vibrations travel through the air in the form of sound waves until they reach our ears. Imagine dropping a pebble in a still pond. The ripples you see on the water are like sound waves traveling through the air.

Now, let's talk about something you know very well - music! When you listen to a song, the sound waves travel from the speakers to your ears, and you hear the music. This is because the sound waves create vibrations in your eardrum which your brain turns into sound.

But it's not just music that creates sound waves! Think about the different noises you hear every day, like birds chirping, cars honking, or dogs barking - they are all made by sound waves too!

Did you know that sound waves can also be used to help us in many ways? For example, doctors use special machines that use sound waves to look inside our bodies. This helps them see if we have any injuries or illnesses.

So, in conclusion, sound waves are the way we hear noises. They are created by vibrations that travel through the air until they reach our ears. We hear the different sounds because our brain turns the vibrations into sound.
