SOUND

Sound

• sound waves move through a medium and particles on the medium vibrate at the same frequency. Hertz is the most common unit used for frequency.
• 1 Hertz= 1vibration/second

Waves

• a sound wave is a compression wave. It has wavelength, amplitude frequency and, velocity just like any other wave.
• the distance from one crest to the other is the waveleght
• amplitude is the measured from the equilibrium

Sound Travel

• sound travels through solid, liquid, and gas.
• sound can not travel in a vacuum
• sound can not travel in space either since molecules and atoms are so far apart it is hard for sound to be detected
• the speed a sound wave depends on the elasticity of that medium.

Longitudinal waves

• Longitudinal waves move in the same direction that a sound waves do

Transverse

• Transverse waves move in different directions
