Electromagnetic radiation is energy propagating through space as coupled, oscillating electric and magnetic fields oriented perpendicular to each other and to the direction of travel, moving at the speed of light in vacuum. It is characterized by wavelength, frequency, and photon energy, which are interrelated, and it exhibits both wave-like and particle-like behavior. Ordered by increasing frequency, the electromagnetic spectrum spans radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. A fundamental distinction separates non-ionizing radiation, such as radiofrequency, microwave, and visible wavelengths, from ionizing radiation of sufficient photon energy to displace electrons and damage molecules including DNA. Interactions with matter—absorption, reflection, scattering, transmission, and the deposition of energy—govern both technological applications and biological effects. Practical uses include wireless and broadcast communication, radar, medical and industrial imaging, materials processing, spectroscopic analysis, and solar energy concentration. Biological consequences depend on frequency, intensity, and exposure duration: ionizing radiation can produce direct molecular damage, while research on non-ionizing radiofrequency exposure examines thermal and possible non-thermal effects in living tissue. Quantifying dose, field strength, and exposure underpins radiation protection, regulatory limits, and safety standards. The study of electromagnetic radiation thus bridges physics, engineering, materials science, and the biological and medical sciences.
