Summary:

• For transverse waves the material motion is perpendicular to the wave’s motion.
• For longitudinal waves the material motion is parallel to the wave’s motion.
• For waves, the material oscillates in place but for flow (wind, for example) the material moves along with the flow.
• The amplitude of a wave is determined by the displacement of the material as it oscillates.
• Various types of scales for wave amplitude exist, such as the decibel scale for sound.
