Phys Wave Properties
TEKS 7a,7b, and 7c
| Term | Definition |
|---|---|
| Wave | A disturbance that travels through a medium from one location to another |
| Harmonic Motion | Motion that repeats periodically |
| Transverse wave | A wave vibrating at right angles to the direction of energy movement. |
| Longitudinal wave | A wave vibrating in the same direction as the energy moves. |
| Velocity | The speed of an object in a given direction. |
| Frequency | The number of waves that pass a fixed place in a given amount of time. |
| Hertz | Unit of frequency; number of waves per second. |
| Period | Number of seconds per one wave cycle |
| Amplitude | The maximum extent of a vibration measured from equilibrium. |
| Wavelength | Distance between successive crests (or same point) on a wave |
| Electromagnetic wave | Transverse waves composed of perpendicular oscillating electric and magnetic fields. |
| Electromagnetic Spectrum | Range of wavelengths or frequencies over which electromagnetic radiation extends. |
| Medium | The substance that waves travel through. |
| Crest | The highest point on a transverse wave. |
| Trough | The lowest point on a transverse wave. |
| Compression | The region in a longitudinal wave where the particles are closest together. |
| Rarefaction | The region in a longitudinal wave where the particles are farthest apart. |
