Unit D:
Sound & Waves
WHAT'S THE BIG IDEA?
- Mechanical waves have specific characteristics and predictable properties.
- Sound is a mechanical wave.
- Mechanical waves can affect structures, society, and the environment in positive and negative ways.

What is elasticity?
- Solids have the strongest interactions between the molecules followed by liquids and gases.
- Therefore solids are more rigid (have higher a elasticity) compared with liquids and gases.
- For this reason sound travels faster in solids than it does in liquids and gases.
