Spectrum first: that's a range.
The range here is the range of the energies of photons (light quanta).
So we're talking about photons,
which are always moving--at the speed of light.
A moving photon can be thought of as two sine waves
stretched out in its direction of travel.
(The planes of the two waves are at right angles,
and they are ninety degrees out of phase.)
One of the waves represents (signed, i.e., plus and minus) electric field intensity;
the other, magnetic field intensity.
The visible spectrum
what does an electromagnetic spectrum consist of
Cosmic rays are not part of the electromagnetic spectrum. They are high-energy particles, such as protons and atomic nuclei, that travel through space at nearly the speed of light. Unlike electromagnetic waves, which are composed of oscillating electric and magnetic fields, cosmic rays are actual particles with mass.
Part of the electromagnetic spectrum can be detected by eye, and we call that bit "light". The thing about electromagnetic radiation is that a varying magnetic field causes a (varying) electric field (that's how power stations make electric current) and a varying electric field causes a (varying) magnetic field. So electromagnetic radiation is what you get when a varying electric field creates a varying magnetic field which in turn contributes the varying electric field. The whole thing then appears as bundled varying electric and magnetic field wave system which propagates at the velocity of light, That is why it is called electromagnetic. There are no magnetic poles or electric charges in it, and it can travel through a vacuum.
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
All waves in the electromagnetic spectrum are forms of electromagnetic radiation that travel at the speed of light, have both electrical and magnetic properties, and can travel through a vacuum. They also all consist of oscillating electric and magnetic fields perpendicular to each other.
The answer is electromagnetic spectrum
Yes, the electromagnetic spectrum includes both electric and magnetic fields. These fields are perpendicular to each other and propagate as waves through space. The interaction between electric and magnetic fields gives rise to electromagnetic radiation, such as visible light, radio waves, and X-rays.
The answer is electromagnetic spectrum

The name given to the range of waves with increasing energies is called the Electromagnetic Spectrumi think it is spectrum

le spectrum
There are electric fields and magnetic fields. If those change over time, the changes may propagate at the speed of light - that's called an electromagnetic wave.
It's in the RF range of the spectrum, but that is a very simplistic answer. This link may help answer your question: http://www.fda.gov/cdrh/ode/primerf6.html TommyTrouble
The entire electromagnetic spectrum frequencies, from the lowest to the highest frequencies, are collectively called the electromagnetic spectrum.
