What Is Electromagnetic Radiation? Electromagnetic waves are formed when an electric field (shown as blue arrows) couples with a magnetic field (shown as red arrows). The magnetic and electric fields of an electromagnetic wave are perpendicular to each other and to the direction of the wave. James Clerk Maxwell and Heinrich Hertz are two scientists who studied how electromagnetic waves are formed and how fast they travel.

What is the difference between the Electromagnetic radiation and an electromagnetic field? The Electromagnetic Spectrum The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.

Nuclear electromagnetic pulse This article is about nuclear-generated EMP. For other types, see Electromagnetic pulse. A nuclear electromagnetic pulse (commonly abbreviated as nuclear EMP, pronounced /iː.ɛm.piː/, or NEMP) is a characteristic burst of electromagnetic radiation created by nuclear explosions.

Electromagnetic radiation Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields that propagate at the speed of light through a vacuum. 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. The wavefront of electromagnetic waves emitted from a point source (such as a lightbulb) is a sphere.

- The Electromagnetic Spectrum The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays.

The Electromagnetic Spectrum Radio Waves. Radio waves are a type of electromagnetic (EM) radiation with wavelengths in the electromagnetic spectrum longer than infrared light . They have have frequencies from 300 GHz to as low as 3 kHz, and corresponding wavelengths from 1 millimeter to 100 kilometers. Like all other electromagnetic waves, radio waves travel at the speed of light. Naturally occurring radio waves are made by lightning or by astronomical objects.

Electromagnetic pulse An electromagnetic pulse (EMP), also sometimes called a transient electromagnetic disturbance, is a short burst of electromagnetic energy.Such a pulse may occur in the form of a radiated, electric or magnetic field or a conducted electric current depending on the source, and may be natural or man-made.n EMP arises where the source emits a short-duration pulse of energy. The energy is usually broadband by nature, although it often excites a relatively narrow-band damped sine wave response in the victim. Some types are generated as repetitive and regular pulse trains.

How do electromagnetic waves travel through a vacuum (Space)? Mechanical waves use the substrate to move along (the medium). Electromagnetic 'waves' are a combination of a particle and a wave (they have the same properties of both) == photons. Electromagnetic waves encompass light, microwaves, radio waves, and gamma waves (to name a few). Since EM particles act as waves, but also have a mass they actually exist in the Space-Time continuum and can travel without a medium.

Nuclear electromagnetic pulse The E1 pulse is the very fast component of nuclear EMP. E1 is a very brief but intense electromagnetic field that induces very high voltages in electrical conductors. E1 causes most of its damage by causing electrical breakdown voltages to be exceeded.n nuclear EMP all of the components of the electromagnetic pulse are generated outside of the weapon. For high-altitude nuclear explosions, much of the EMP is generated far from the detonation (where the gamma radiation from the explosion hits the upper atmosphere).

- No. Electromagnetic waves are part of a spectrum of energy waves that include radio waves, infra red, visible light through to ultraviolet and microwaves and gamma radiation.… Ultrasound waves are high frequency (beyond human hearing range) that are generated by vibration of crystals.s the electric and magnetic fields move back and forth, they create the same waves being emitted from them. They waves are called electromagnetic waves/radiation. There are 7 classifications of these waves. Radiowaves, microwaves, infrared, visible light, ultraviolet light, X-rays, and gamma rays.

Radiant energy Because electromagnetic (EM) radiation can be considered to be a stream of photons, radiant energy can be viewed as the energy carried by these photons. Alternatively, EM radiation can be viewed as an electromagnetic wave, which carries energy in its oscillating electric and magnetic fields. These two views are completely equivalent, and are reconciled to one another in quantum field theory.

Electromagnetic Waves The waves are defined as the disturbance through any medium of substance. The electromagnetic waves are the waves which are generated by coupling of magnetic field with electric field. These waves are in perpendicular direction to both the electric and magnetic and also perpendicular to each other.

Electromagnetic field For the British hacker convention, see Electromagnetic Field (festival). An electromagnetic field (also EMF or EM field) is a physical field produced by electrically charged objects. It affects the behavior of charged objects in the vicinity of the field. The electromagnetic field extends indefinitely throughout space and describes the electromagnetic interaction.
