Basic Electromagnetic Wave Properties - Electromagnetic radiation is characterized by a broad range of wavelengths and frequencies, each associated with a specific intensity (or amplitude) and quantity of energy.
The Electromagnetic Spectrum. The electromagnetic (EM) spectrum is the scientific name for types of photon radiation. Electromagnetic radiation consists of photons (light particles) that travel in a wave-like pattern at the speed of light. The amount of energy found in these photons forms the various types of electromagnetic radiation in the spectrum, which is expressed in terms of energy, wavelength or frequency.
