A Self-Guided Tour of the Electromagnetic Spectrum 3dm Name: Date: Period: A wave can be described as a disturbance that travels through a medium from one location to another location . (\Ag-lloQniCfll waves require matter to travel through (a medium ), while fc_M_ waves do not . A mechanical wave is created when a source of energy causes a vibration to travel through a medium . Electromagnetic waves are produced when an electric charge vibrates or accelerates. The transverse waves consist of changing electric and magnetic fields, which travel to one another. Radio Waves 1 .
