Waves vocabulary
| Term | Definition |
|---|---|
| Wave | Is a disturbance of energy as it transfers from place to place. |
| Electromagnetic waves | waves are a form of radiation that travel though the universe. The waves, magnetic and electric, are perpendicular from each other. They are a wave when the electricity or the magnetism moves or changes Examples of electromagnetic waves are radio waves, |
| Medium | A medium is any kind of matter that is disturbed by energy |
| Mechanical waves | Mechanical waves are ocean waves, seismic waves, sound waves, and slinky waves, all require matter or medium) because they need a medium to move through. |
| Compressional waves | Also known as Mechanical/longitudinal |
| Compressional waves | displace matter back and forth in the same direction as the energy of the wave. |
| Transverse wave | A transverse wave carries the energy at a right angles to the direction of the energy flow. (Ocean waves-requires a medium) and most electromagnetic waves, light-which requires no medium) move in a transverse pattern. |
| Crest | The crest is the highest point on a wave. |
| Trough | The trough is the lowest point on a wave. |
| Amplitude | The distance between the rest line and the crest or the rest line and the trough is the amplitude. |
| Wavelength | The wavelength is the distance between two crests or two troughs. Or compression to compression or rarefaction to rarefaction. |
| Frequency | The frequency is the number of waves that pass by a given point in one second measured in hertz or waves per second. |
