When the particles in a material are bunched together (high pressure).
When the particles in a material are widely spaced (low pressure).
Maximum [amplitude?] of a wave
The minimum [amplitude] of a wave.
Position about which an oscillator oscillates.
Phase (radians of degrees)
How far an oscillator is through a cycle.
Difference between the phases of two waves/oscillators.
Displacement is parallel to the direction of energy transfer.
Displacement is perpendicular to the energy transfer.
