Sound
What is sound?
a form of energy
vibrating molecules that form a pattern
longitudinal/compressional
Properties of sound:
pitch
how high or low a sound is
measured in Hz
loudness
how well a sound can be heard
depends on amplitude
measured in decibels
doppler effect
closer = higher pitch
farther away = lower pitch
How It Travels
through all forms of matter
fastest through solid (then liquid, then gas)
b/c molecules are so tightly packed together
can't travel in a vacuum (no sound in space)
