| Wave | A disturbance that carries energy through matter or space |
| Medium | The matter through which a wave travels |
| Mechanical Waves | Waves that require an medium |
| Electromagnetic Waves | Waves that consist if changing electric and magnetic fields in space;does not require a medium (example:light waves) |
| Transverse Waves | Waves in which the motion if the particles is perpendicular to the motion of the wave as a whole |
| Longitudinal Waves | Wave that caues the particles in the medium to vibrate parallel to the direction of the wave motion |
| Crests | The highest point of a transverse wave |
| Amplitude | The greatest distance that particles are displaced from their normal resting positions because of a wave |
| Wavelength | The distance from one crest of a wave to the next crest, or from one trough to the next trough |
| Period | The time required for one full wavelength of a wave to pass a certain point |
| Frenquency | The number of full wavelengths that pass a point ina given time interval |
| Wave Speed | How fast a wave moves |
| Doppler Effect | An observed change in the frequency of a wave resulting from the motion of the source of the observer |
| Reflection | The bouncing back of a wave when it meets a surface or boundary |
| Diffraction | The bending of waves when they pass an edge |
| Refraction | The bending of waves when they pass from one medium into another |
| Interference | The combination of waves, in the same motion, to produce a single, new wave that is different from the original wave |
| Constructive Interference | Interference in which, waves combine so the resulting waves amplitude is bigger that the sum of the original wave |
| Destructive Interfererence | Interference in which, waves combine so the resulting waves amplitude is smaller than the larger of the two waves |
| Standing Waves | Waves formed when reflected waves with the same amplitude, frequency, and speed as teh original waves |
