Sound is like a ripple in water. When you speak, your voice pushes the air around you, and that makes ripples, we call them sound waves. These ripples can bend slightly when they hit something, just like how water bends around the edge of a pool. That’s why even though you are not facing someone directly, they can still hear you if you’re in the next room.
Examples
- Your mom calls you from the kitchen, she’s not facing you, but you still hear her.
- A teacher speaks at the front of the room, even if you're sitting in the back, you can still hear them clearly.
- You shout across a hallway and someone answers from around the corner, sound traveled there without needing to be pointed directly at them.
