A full transverse wave consist of one crest and one trough.
		+
		+	====Longitudinal====
		+	Longitudinal waves travel parallel to the disturbance - for example, sound waves.<ref name="Aid" /> Compressions and rarefactions are to longitudinal waves as crests and troughs are to transverse waves, thus a full longitudinal wave consist of one Compression and one rarefaction. Compressions are areas of high pressure, and rarefactions are areas of low.
		+
		+	====Surface====
		+	Surface waves are transverse waves and longitudinal waves mixed into one medium.<ref name="Chptr. 8" />
		+	===Electromagnetic===
		+	Electromagnetic waves are waves that do not require a medium.
		+	===Matter===
		+	[[Matter]] waves are produced by electrons.
		+	==Wave Collisions==
		+	When two or more waves collide, the result determines the type of collision. If the amplitudes of each wave are in the same direction (i.e. two crest or two troughs) - a larger amplitude will result, called constructive interference. If the amplitudes are in opposite directions, then a smaller amplitude will result, called destructive interference.<ref name="Chptr. 8" />
		+	==Key Terms==
		+
		+	The amplitude of a wave is the height of the displacement.<ref name="Aid" />
		+
		+	The velocity of a wave is how quickly the wave travels.
		+
		+	The frequency of a wave is how many waves pass in one second, and conversely, the period of a wave is how many seconds it takes for one wave to show up. The period is the inverse of the frequency and vice versa.
		+
		+	The wavelength (represented by the Greek symbol lambda - λ) is the length of one wave in meters.
