Energy and the Electromagnetic Spectrum
The electromagnetic spectrum is the result of the scattering of solar rays into different colors like in a rainbow or in a prism glass. The white light from the sun divides into its constituent colors or the so-called spectrum.
The concept of electromagnetic spectrum arises from the specific nature of light. The following two complementary theories explicitly describe light: the corpuscular theory and the wave theory. It is worth mentioning that none of these approaches can entirely explain and account for all the various light's properties. Needless to say, there are properties of light whose explains are best portrayed in the corpuscular theory and there are those that the wave theory describes perfectly.
Moreover, the term electromagnetic spectrum is applicable when talking about light because the propagation of light takes the form of both electric and magnetic forces.
The next section focuses on the wave theory and expounds on the concept of electromagnetic radiation.
