ORIGIN RED ALERT 2 GAME SPEED FREE
Electromagnetic radiation is associated with those EM waves that are free to propagate themselves ("radiate") without the continuing influence of the moving charges that produced them, because they have achieved sufficient distance from those charges. EM waves carry energy, momentum and angular momentum away from their source particle and can impart those quantities to matter with which they interact. Įlectromagnetic waves are emitted by electrically charged particles undergoing acceleration, and these waves can subsequently interact with other charged particles, exerting force on them. In order of increasing frequency and decreasing wavelength these are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. Electromagnetic waves of different frequency are called by different names since they have different sources and effects on matter. The position of an electromagnetic wave within the electromagnetic spectrum can be characterized by either its frequency of oscillation or its wavelength. In homogeneous, isotropic media, the oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. In a vacuum, electromagnetic waves travel at the speed of light, commonly denoted c. Depending on how this periodic change occurs and the power generated, different wavelengths of electromagnetic spectrum are produced. Electromagnetic radiation or electromagnetic waves are created due to periodic change of electric or magnetic field. Ĭlassically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields. All of these waves form part of the electromagnetic spectrum.
It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays. In physics, electromagnetic radiation ( EMR) consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy.
