Waves vocab
the vocabulary of Waves :)
| Term | Definition |
|---|---|
| wave | energy that is transferred from place to place when a disturbance has been made |
| energy | energy that is transferred from place to place when a disturbance has been made |
| medium | a material that allows waves to travel through it |
| mechanical wave | a wave that has to have a medium to travel through |
| vibration | a repeated back-and-forth or up-and-down motion |
| transverse wave | a wave that makes the medium move at right angles in the direction of the wave |
| crest | a wave that makes the medium move at right angles in the direction of the wave |
| trough | The lowest point of a wave |
| longitudinal waves | they move the medium parallel to the direction in which the waves are traveling |
| compression | when the particles are closer together in a longitudinal wave |
| refraction | when the particles are further apart in a longitudinal wave |
| amplitude | maximum distance that the particles of the of the medium carrying the wave move away from their possible rest position |
| wavelength | distance between two corresponding parts of a wave |
| frequency | number of complete waves that pass a given point at a given time |
| hertz (Hz) | unit of measurement for frequency |
| reflection | when an object or wave hits a surface through which it cannot pass, it bounces back |
| refraction | The bending of waves due to a change in speed. |
| diffraction | When a wave moves around a barrier or through an opening barrier, it bends and spreads out |
| interference | The interaction between waves that meet. |
| consructive interface | The interference that occurs when waves combine to make a wave with a larger amplitude. |
| destructive interface | the interface that occurs when two waves combine to make another 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 | the point of zero amplitude on a spaced along wave |
| antinode | the point of maximum amplitude on a standing wave |
| resonance | an increase in the amplitude of a vibration that occurs when external vibrations match an object’s natural frequency |
| seismic wave | Waves that are made from earthquakes |
| P waves | A seismic wave that is longitudinal |
| S waves | Seismic waves that are transverse (secondary waves) |
| surface wave | A wave that travels the surface of a medium and is a combo of longitudinal and transverse wave |
| tsunami | A very large surface wave |
| seismogragh | A instrument that can measure and detect earthquake waves |
| law of reflection | A rule that states the angle of reflection equals the angle of incidence |
