Period
Number of seconds per wave (Seconds/waves)
Medium
Material a wave travels (Solid, liquid, gas)
Transverse waves
Perpendicular waves
Resonance
Natural frequency (vibration)
Mechanical wave
Requires medium (determines speed)
Longitudinal wave
Parallel waves
Amplitude
Volume (loudness) of a second spectrum
Inverse
Relationship between frequency and period
