| | Term | Definition |
|---|---|---|
| |
Wave | A disturbance that transfers energy from place to place |
| |
Energy | The ability to work |
| |
Medium | Material through which a wave travels |
| |
Mechanical wave | A wave that requires a medium through which to travel |
| |
Vibration | A repeated back-and-forth or up-and-down motion |
| |
Transverse wave | A wave that moves the medium in a direction perpendicular to the direction in which the wave travels |
| |
Crest | The highest part of a transverse wave |
| |
Trough | The lowest part of a transverse wave |
| |
Longitudinal wave | A wave that moves the medium parallel to the direction in which the wave travels |
| |
Compression | The part of a longitudinal wave where the particles of the medium are close together |
| |
Rarefaction | The part of a longitudinal wave where the particles of the medium are far apart |
| |
Surface wave | A wave that occurs at the surface between two mediums |
| |
Amplitude | The maximum distance the particles of a medium move away from their rest positions as a wave passes through the medium |
| |
Wavelength | The distance between two corresponding parts of a wave |
| |
Frequency | The number of complete waves that pass a given point in a certain amount of time |
| |
Hertz (Hz) | Unit of measurement for frequency |
| |
Reflection | The bouncing back of a wave when it hits a surface through which it cannot pass |
| |
Angle of incidence | The angle between an incoming wave and an imaginary line drawn perpendicular to the surface of the new medium |
| |
Angle of reflection | The angle between a reflected wave and an imaginary line drawn perpendicular to the surface of the new medium |
| |
Refraction | The bending of waves as they enter a different medium |
| |
Diffraction | The bending of waves around a barrier |
| |
Interference | The interaction between waves that meet |
| |
Constructive Interference | The interference that occurs when two waves combine to make a wave with a larger amplitude |
| |
Destructive Interference | The interference that occurs when two waves combine to make a wave with a smaller amplitude |
| |
Standing wave | A wave that appears to stand in one place, even though it is really two waves interfering as they pass through each other |
| |
Node | A point of zero amplitude on a standing wave |
| |
Antinode | A point of maximum amplitude on a standing wave |
| |
Resonance | The increase in the amplitude of vibration that occurs when external vibrations match the object’s natural frequency |
| |
Seismic wave | A wave produced by an earthquake |
| |
Primary wave | A longitudinal seismic wave |
| |
Secondary wave | A transverse seismic wave |
| |
Tsunami | Surface wave on the ocean caused by an underwater earthquake |
| |
Seismograph | Instrument used to detect and measure earthquakes |

13edillon : quik, call the newspapers
13edillon : and tell them to report this mostrosity
13edillon : i'm teting my lawyer this very minute to report this
13edillon : hmph
13edillon : all i was trying to do was mke 1,000 smiles as to cover up the ad frowns around the world.
13edillon : but quizlet ruined my pans
13edillon : quizlet you will rule the day that you denied me, 13edillon to make 1,000 smiles. i will get revenge. *cackles wildly* i will get REVENGE!!!
