| transverse wave | Waves in which the particles vibrate in up and down or perpendicular movement. |
| trough | the lowest point between each crest |
| medium | a substance through which a wave can travel |
| vibration | a repetitive back and forth motion of an object |
| wave | a distubance in a substance, solid,liquid or gas as energy is transmitted through a medium |
| crest | the highest point of a transverse wave |
| wave speed | the speed at which a wave travels |
| frequency | the number of waves produced in a given amount of time |
| amplitude | the maximum distance that the particles of a wave's medium vibrate from their rest position |
| wavelength | the distance from any point on a wave to an identical point on the next wave |
| reflection | the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through |
| interference | the combination of two or more waves that results in a single wave |
| resonance | a phenomenon that occurs when two objects naturally vibrate at the same frequency |
| diffraction | a change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening |
| refraction | the bending of a wave as the wave passes between two substances in which the speed of the wave differs |
| standing wave | a pattern of vibration that simulates or acts like a wave standing still |
| destructive interference | when the troughs of one wave and the troughs of another wave overlap |
| constructive interference | when the crests of one wave overlap the crests of another wave or waves |
