Sound is like vibrations or little "shakes" that move through things.

Think of hitting a drum — it shakes, and those shakes move through the air to your ears!

🚀 Now, let’s see how sound moves in different stuff:

1. Solid (like metal or wood):

• Sound travels very fast! 🏃💨

• Solids are like tightly packed friends holding hands. When one shakes, all others shake quickly.

• Example: If you tap one end of a metal rod, the other end “feels” it super fast!

  
  

2. Liquid (like water):

• Sound moves medium speed. 🐟💧

• The friends (water particles) are a bit apart, so it takes more time to pass the shake.

• Example: Whales can hear each other from very far away in the ocean!

  
  

3. Gas (like air):

• Sound travels slowest here. 🐢🌬️

• Air particles are like lazy friends standing far apart. So, the shake takes time to go from one to the other.

• Example: We hear people talking in air — it works, but it’s slower than in solids.

  
  

⚠️ Important:

• No air = no sound. That’s why sound doesn’t travel in space! 🪐🚫🔊
