How Sound Travels Across Different Mediums?

Sound is like a whisper that wants to be heard, and it travels by pushing things around in different mediums.

Imagine you're playing with your favorite toy car on the floor. When you push it, it rolls smoothly across the hard floor. But if you roll it onto a soft carpet, it slows down because the carpet is squishier and doesn’t let the car go as fast. That’s like how sound waves move through different things, some are easier for sound to travel through than others.

When you shout "Hey!" across the room, your voice makes tiny pushes in the air called vibrations, and those vibrations move through the air until they reach someone’s ears. It's like sending a message by pushing small friends who then push more friends, all the way to the other side.

If you shout underwater, your voice travels faster because water is tighter than air, it’s easier for vibrations to move through tight spaces. It’s like running on a smooth track instead of a bumpy road!

When you put your ear against a table and someone taps the other side, you hear it clearly because solids pass sound even better, they're super tight!
