WebAug 4, 2016 · One of the main characteristics which defines an electromagnetic field (EMF) is its frequency or its corresponding wavelength. Fields of different frequencies interact with the body in different ways. One can imagine electromagnetic waves as series of very regular waves that travel at an enormous speed, the speed of light. In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. Types of EMR include radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays, all of … See more Theory Maxwell's equations James Clerk Maxwell derived a wave form of the electric and magnetic equations, thus uncovering the wave-like nature of electric See more EM radiation (the designation 'radiation' excludes static electric and magnetic and near fields) is classified by wavelength into radio, microwave, infrared, visible, ultraviolet See more The basic structure of matter involves charged particles bound together. When electromagnetic radiation impinges on matter, it causes the … See more Electromagnetic waves are predicted by the classical laws of electricity and magnetism, known as Maxwell's equations.
