compression wave | the name of a sound wave due to the vibrations that are in the same direction as the motion and speed of the wave. |
Medium | is the material through which sound energy moves. Media may be solid, liquid or gas. |
solid | the phase of matter that sound moves through the fastest |
gas | the phase of matter that sound moves through the slowest |
Pitch | is the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone. |
Vibration | is the back and forth movement of molecules. |
Wavelength | is the distance between the same point in two waves. |
Waves | are disturbances moving through a medium (solid, liquid, or gas). |
Sound | is a form of mechanical energy produced and transmitted by vibrating matter. |
higher pitch | objects that vibrate faster |
lower pitch | objects that vibrate slower |
