Introduction
Electromagnetic waves (EM waves), also referred to as electromagnetic radiation, are the combination of both electric waves and magnetic waves thus, electromagnetic. Radiation in general can be either alpha, beta or gamma rays, gamma rays are the EM waves, so this site will be covering gamma ray radiation. "Electromagnetic radiation has properties of both waves and particles" (The Kingfisher Science Encyclopedia). This site will focus on small areas of the wave properties of the following: Light, Heat, and Radio EM Waves.
Below is a picture of the EM spectrum as well as the color spectrum. The color spectrum will be discussed on the light page of this site. The EM radiation is a wide spectrum from longer wavelengths (lower frequency) to shorter wavelengths (higher frequency).
As presented by the McGraw-Hill Encyclopedia of Science and Technology a definition of electromagnetic radiation, "energy transmitted through space or through material medium in the form of electromagnetic waves. The term can also refer to the emission and propagation of such energy. Whenever an electric charge oscillates or is accelerated, a disturbance characterized by the existence of electric and magnetic fields propagates outward from it. This disturbance is called electromagnetic wave" (vol. 6, 154).
