|
Medium |
Substance through which the wave moves |
|
|
Wave pulse |
A small part of a wave (crest or trough) that can be produced by a sudden displacement of a medium from its equilibrium position |
|
|
Equilibrium |
Undisturbed surface of a medium |
|
|
Crest |
A rise in medium above equilibrium |
|
|
Trough |
Points of the wave lower than equilibrium |
|
|
Amplitude |
Magnitude of greatest displacement from equilibrium |
|
|
Wave length |
Distance between two successive crests or troughs |
|
|
Wave front |
Leading edge of a wave |
|
|
Incident wave |
A wave front moving out from the point of origin toward a barrier |
|
|
Reflected wave |
A wave front moving away from the barrier |
|
|
Mechanical wave (simply wave) |
Waves that require a medium in which to travel |
|
|
Transverse wave |
Moves perpendicular to the medium in which it travels |
|
|
Longitudinal waves |
Wave that moves parallel to the medium |
|
|
Rarefractions |
Areas where the components of a medium are further apart than in equilibrium position |
|
|
Compressions |
Areas where the components of a medium are closer together than in equilibrium position |
|
|
Rays |
Lines indicating only the direction of motion of the wave front at any point where the ray and the wave front intersect |
|
|
Diverging rays |
Rays that spread out as they move away from the origin |
|
|
Oscillation |
One complete oscillation is called a cycle |
|
|
Period (T) |
The time required for one complete oscillation |
