📚 Quick Study Guide

  • 🔊 What is an Echo? An echo is a sound that bounces back to you. Think of it like shouting in a canyon!
  • ⛰️ Where do Echos Happen? Echos happen when sound waves hit a hard surface, like a wall, a mountain, or even a building.
  • 📏 How Far Away? You need some distance for an echo to be clear. If you're too close to the wall, you won't hear a distinct echo.
  • 👂 Hearing Echos: The sound travels from you to the surface and back to your ears. That's the echo!
  • 💡 Fun Fact: Some animals, like bats and dolphins, use echos to find things! This is called echolocation.
