Sound waves move differently in solids, liquids, and gases. This happens because of how tightly packed and structured these materials are.

1. Speed of Sound:

   • In Solids: Sound can travel really fast, up to 5,000 meters per second. Think of steel!
   • In Liquids: Sound moves at about 1,500 meters per second. Water is a good example.
   • In Gases: Here, sound travels the slowest, around 340 meters per second. Air is what we breathe every day.

2. Density and Strength:

   • Sound is quickest in solids because the particles are close together. This closeness helps them move energy quickly.
   • Liquids are less packed than solids but more so than gases. That's why sound travels at a medium speed in liquids.
   • Gases are the least packed, which is why sound travels more slowly in them.

3. Frequency:

   • The frequency of sound waves stays the same no matter if it’s in solids, liquids, or gases. What changes is how fast the sound moves.
