Wave | A periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium |
Medium | A physical environment in which phenomena occur |
Mechanical Wave | A wave that needs a medium in which to travel |
Transverse Wave | A wave in which the particles of the medium move perpendicularly to the direction the wave is traveling |
Longitudinal Wave | A wave in which the particles of the medium vibrate parallel to the direction of wave motion |
Compression | Part of the longitudinal wave where the particles bunch up close together |
Rarefraction | Part of the longitudinal wave in which of the particles expand and move apart |
Electromagnetic Wave | A wave that consists of electric and magnetic fields that vibrate at right angels to each other |
