| Wave | Traveling disturbance that carries energy from one place to another |
| Vibrations | Back and forth motion that starts a wave |
| Mechanical | Waves that require a medium |
| Electromagnetic | Waves that disturb electric and magnetic fields; do NOT require a medium |
| Medium | Matter or substance through which a wave travels |
| Crest | Highest point on a wave |
| Trough | Lowest point on a wave |
| Transverse | Waves in which the motion of the particles in the medium are at right angles (perpendicular) to the motion of the wave |
| Longitudinal | Waves in which the motion of the particles in the medium are parallel to the motion of the wave |
| Transverse Wave Example | Flicking a rope, all electromagnetic waves |
| Longitudinal Wave Example | Sound Waves |
| Surface | Waves which move particles in the medium in a circular motion |
| Surface Wave Example | Ocean waves |
| Mechanical Wave Examples | Ocean Waves, Sound Waves, and Seismic Waves |
| Electromagnetic Wave Examples | Light, Microwaves, X-rays, UV light, Radio and TV signals |
| Medium States of Matter | Solid, Liquid, or Gas |
| Transverse Wave | S-Wave (Seismic Wave) |
| Longitudinal Wave | P-Wave (Seismic Wave) |
| Surface Wave | L-Wave (Seismic Wave) |
| Compression | Part of the wave where the particles are crowded together |
| Rarefaction | Part of the wave where the particles are spread apart |
