===Mechanical===

Mechanical waves require an [[environment]] to travel through - called a medium. The medium's [[density]], [[elasticity]] and [[temperature]] determine velocity. Matter with the most elasticity, least density and highest temperature would create the fastest wave.<ref name="Chptr. 8">{{cite web|url=http://library.thinkquest.org/10796/ch8/ch8.htm|title=Waves|format=HTML|language=English|accessdate=2007-09-28|work=Learn Physics Today}}</ref>

====Transverse====

Transverse waves travel perpendicular to the disturbance.<ref name="Aid">{{cite web|title=A wave|url=http://www.scienceaid.co.uk/physics/waves/properties.html|format=HTML|language=English|accessdate=2007-09-28|work=Science Aid⁺}}</ref> For example, if the end of a [[slinky]] is moved up and down, a transverse wave will be created, because although the disturbance is vertical, the wave will travel horizontally across the slinky. Transverse waves have crests (each parabola's tip in the slinky if the parabola is above where the slinky would usually be) and troughs (each parabola's low point in the slinky if the parabola is below where the slinky would usually be). A full transverse wave consist of one crest and one trough.

The wavelength (represented by the Greek symbol lambda - λ) is the length of one wave in meters.
