What is the Electromagnetic Spectrum or Electromagnetic Radiation?
The “electromagnetic spectrum” term is used to describe the electromagnetic radiation of all wavelengths. This includes microwaves, radio waves, infrared, visible light, ultraviolet, x rays, gamma rays, and other electromagnetic radiation of longer and shorter wavelengths. It is important to say that the only difference between any portions of the electromagnetic spectrum is the wavelength. For example, a radio wave is electromagnetic radiation of a long wavelength and x rays are electromagnetic radiation of a shorter wavelength, but their behavior is the same. However, even though all portions of the electromagnetic spectrum follow the same laws, their different energies and their different wavelengths allow them to have different effects on matter. The variety of the electromagnetic spectrum is a result of the same laws applied to different energies and wavelengths. Electromagnetic radiation has a dual nature, as both particles and waves. Another way to look at it, is as changing ele
