|
Transverse Wave |
A wave vibrating at right angles to the direction of its propagation. |
Must have a medium |
|
|
Compressional Wave |
A longitudinal wave (as a sound wave) propagated by the elastic compression of the medium —called also compression wave. |
Sound Wave |
|
|
Crest |
highest point |
Opposite of a tough |
|
|
Trough |
A lowest point |
Opposite of a crest |
|
|
Compression |
the reduction in volume (causing an increase in pressure) of the fuel mixture in an internal combustion engine before ignition. |
Like compressional wave |
|
|
Rarefaction |
Rarefaction is the reduction of an item's density, the opposite of compression. |
|
|
|
Frequency |
the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second. |
Used with pitch |
|
|
Amplitude |
the maximum extent of a vibration or oscillation, measured from the position of equilibrium. |
|
|
|
Wavelength |
the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave. |
|
|
|
Medium |
Makes vibration |
Makes noise |
|
|
Electromagnetic Wave |
one of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity and that include radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays. |
|
|
|
Mechanical Wave |
A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. |
|
|
|
Pitch |
the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone. |
Work with frequency |
|
|
Refraction |
he fact or phenomenon of light, radio waves, etc., being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density. |
|
|
|
Absorption |
the process or action by which one thing absorbs or is absorbed by another. |
|
|
|
Reflection |
the throwing back by a body or surface of light, heat, or sound without absorbing it. |
|
|
|
Doppler Effect |
an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astronomers. |
