Catch a Wave List 1
Term | Definition |
---|---|
Energy | Ability to cause changes in matter |
Wave | A disturbance or vibration of a medium that moves through the medium |
Electromagnetic Wave | Transverse wave consisting of vibrating electric and magnetic fields that can travel across space |
Mechanical/Physical Wave | A disturbance in matter that transfers energy from place to place; starts when matter is disturbed |
Vibration | Rapid back and forth movement |
Medium | Materials(series of interconnected particles) through which a wave travels |
Light | Electromagnetic radiation that can be perceived by the human eye |
sound | Transfer of energy from a vibrating object in longitudinal waves that travel through matter |
Earthquake/seismic | A sudden movement of the Earth's lithosphere (its crust and upper mantle) |
Longitudinal Wave | Wave in which particles of the medium vibrate in the same direction that the wave travels |
Transverse Wave | Wave in which particles of the medium vibrate at right angles to the direction that the wave travels |
Wavelength | Can be measured as the distance betweeen two adjacent crests of a transverse wave or two adjacent compressions of a longitudinal wave |
Trough | The lowest point of a transverse wave |
Crest | The highest point of a transverse wave |
Amplitude | The maximum distance the particles of a medium move from their resting position |
Frequency | The number of waves that pass a fixed point in a give amount of time; measured in hertz (Hz) |
Compression | The densest part of a longitudinal wave; force that tends to shorten or squeeze something, decreasing its volume |
Rarefaction | The part of a longitudinal wave that is more spread out; a decrease in density and pressure in a medium, such as air, especially when caused by the passage of a wave |
