A spectrum is a representation of the range of frequencies/wavelengths present in electromagnetic radiation. It may be plotted as the power or intensity on the vertical axis, and the wavelength or frequency on the horizontal axis.
When talking about the electromagnetic spectrum it is sometimes presented as a chart or table showing the range of frequencies/wavelengths that are covered by electromagnetic radiation. Thus it represents radiation from radio frequencies through infra red, visible light, ultraviolet light, x-rays and gamma radiation.
Where does it come from? The first link below shows the history of "spectrum" which was originally used to refer to the colours of light when split up by a rainbow or prism. It was later used by analogy to refer to "a range of objects". I guess that someone just wanted to make a chart showing how the various radiation types are related.
Anything with an electromagnetic field. Magnetism and electricity are two halves of the same coin, you can't have one without the other. From the Sun to your little hearing aid battery, there are lots of things that either absorb or emit electromagnetic fields.
All the energy that we use around here comes from the sun, or came from the sun
a long time ago and was stored underground in the form of dead dinosaurs.
That "wave" is energy traveling from one place to another
carried by a moving set of electric and magnetic fields.

The transfer of energy by electromagnetic waves?
The waves that are the most infictint are the seismic waves
1 What types of waves are light and electromagnetic waves?
The type of waves that are electromagnetic are the visible light waves
How do raidiators in homes transfer heat?
Radiators transfer heat by electromagnetic waves. The sun waves/rays send electromagnetic waves.
How are em waves different from mechanical waves?
mechanical waves need a medium to travel through, electromagnetic waves do not. Electromagnetic waves can travel through space, mechanical waves can not.:PElectromagnetic waves do not require a medium, but mechanical waves do.
Can electromagnetic spectrum waves travel through air?
Yes. Electromagnetic spectrum waves reach your eye through the air.
What kind of waves do x-rays come from?
X-rays are electromagnetic waves.
What are 3 waves of radiation that come from the sun?
Electromagnetic waves found in sunlight are light waves, ultraviolet waves and cosmic waves.
How are electromagnetic waves different to radio waves?
Radio waves ARE electromagnetic waves.
How are electromagnetic waves transfered?
Electromagnetic waves are transferred by electromagnetic radiation.
Are suns rays mechanical waves or electromagnetic waves?
Electromagnetic waves
What happens when electromagnetic waves come in contact with an object?
When electromagnetic waves come in contact with an object, several things can happen depending on the properties of the object. The waves can be absorbed, reflected, transmitted, or refracted by the object. The interaction is determined by factors such as the material of the object, the frequency of the waves, and the angle of incidence.
What do electromagnetic waves do?
Electromagnetic waves transfer energy.
Does light travel as electric waves convex waves luminescent waves or electromagnetic waves?
electromagnetic waves
What is another name for electromagnetic energy?
Another name for electromagnetic energy is radiation. It refers to the waves of energy that compose electromagnetic fields, including light, radio waves, and X-rays.
How are waves transferred?
Electromagnetic waves are transferred by electromagnetic radiation.
What electromagnetic waves have the longest wavelengths?
Radio waves have the longest wavelengths among electromagnetic waves.
The transfer of energy by electromagnetic waves?
The waves that are the most infictint are the seismic waves
