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. |
