- Sound travels as a longitudinal wave- the particles in the medium vibrate in the direction of the wave's movement
- Sound needs vibrations
- Lower pitch = more particles vibrate
- Higher pitch = less particles vibrate
- The more particles the faster sound travels
- Vibrations through solids travel faster than vibrations through air
- Sound is energy
- The particles in the medium either bunch-up together or spread apart in response to the vibrating object
- Reflection of sound = echo
