	Waves propagate through a variety of different mediums. This propagation simply means that a series of wave '''pulses''' - or a single disturbance, think of a single "bump" if a rope is moved up and down - are connected together to form a series of disturbances with crests and troughs that form a wave. This wave vibrates up and down in a periodic manner, creating the stereotypical wave "shape". This wave shape consists of a peak, the highest point that a wave reaches, and a trough, the lowest point that a wave reaches. When combined, this peak and trough create a wave cycle equal to one [[wavelength]].		Waves propagate through a variety of different mediums.

	==Energy Transportation==		==Energy Transportation==
	As waves move from one place to another, they carry energy. Generally, the medium itself doesn't move much as it is the disturbance that is being transmitted. For example, sound waves make the air [[molecule]]s vibrate, but it doesn't move air the way that [[wind]] does. Since the particles of the medium itself don't move, just vibrate, waves are said to be a type of energy transport phenomenon. This means that a disturbance moves through a medium [[particle]] to particle, moving energy across a distance during this process. When particles stop moving from the disturbance, they have the same amount of energy they began with and thus vibrated momentarily only to move energy.<ref name="RE1"/>		As waves move from one place to another, they carry energy.

Waves propagate through a variety of different mediums.

This wave shape consists of a peak, the highest point that a wave reaches, and a trough, the lowest point that a wave reaches. When combined, this peak and trough create a wave cycle equal to one [[wavelength]].

The University of Colorado has graciously allowed us to use the following PhET simulation below. In this simulation, different types of waves can be created by moving the wrench on the left-hand side of the screen.
