Sound Energy
Transmission-how sound moves
1. Sound is made by vibrations.
2. These vibrations make the air particles next to it vibrate, which starts a wave, which travel to our ears.
3. Unlike light, sound needs a medium (like air) to travel through.
Reflection-When sound is reflected it bounces around (like an echo).
Example:
Absorption-When a sound is absorbed (like the acoustic tiles in the music room).
*We are surrounded by sound vibrations, but we can only hear some of them.
Pitch-How fast or slow the vibrations are
The faster the vibration, the higher the pitch.
The slower the vibration, the lower the pitch.
