The Solar Energy Resource

  • Brian Norton


Though all substances continuously emit electromagnetic radiation, the dominant form that such energy takes depends upon its nature and the form of the applied external excitation; electrical conductors emit radio waves when excited by an alternating current; certain elements emit X-rays if excited by atomic bombardment; if elevated to a sufficiently high temperature all substances will emit visible light. Cosmic rays, X-rays, γ-rays, visible light, radio waves etc. are all different forms of electromagnetic radiation. Figure 2.1.1 delineates the entire electromagnetic wave spectrum.
