| wave | A disturbance that transmits energy through matter or space. |
| medium | a substance through which a wave can travel. |
| transverse wave | The particles of the wave's medium vibrate perpendicular to the direction the wave is traveling. |
| longitudinal wave | The particles of the medium move parallel to the direction in which the wave travels. |
| amplitude | The maximum distance a wave vibrates from its rest position. |
| wavelength | The distance between one point on a wave and the corresponding point on an adjacent wave. |
| frequency | The number of waves produced in a given amount of time. |
| wave speed | The speed at which a wave travels. |
| reflection | The bouncing back of a wave after it strikes a barrier or an object. |
| refraction | The bending of a wave as it passes at an angle from one medium to another. |
| diffraction | The bending of waves around a barrier or through an opening. |
| interference | A wave interaction that occurs when two or more waves meet and overlap. |
| standing wave | A wave that appears to stand in one place. |
| resonance | The vibrations traveling through an object match the object's natural frequency. |
