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.

What is the definition of eletromagnetic?
It depends what you are talking about... Electromagnetic field Electromagnetic force Electromagnetic radiation Electromagnetic spectrum Electromagnetic therapy Electromagnetic waves ...they each have different meanings.
What is the arrangement of electromagnetic waves according to their wavelengths and frequencies called?
That's called the electromagnetic spectrum.
What does a electromagnetic spectrum contain of?
what does an electromagnetic spectrum consist of
What energy does the electromagnetic spectrum make?
the energy that makes the electromagnetic spectrum is electromagnetic radiation
What does the electromagnetic spectrum have?
Electromagnetic spectrum have different electromagnetic waves classified orderly according to their wavelength or frequency.
What region of the electromagnetic spectrum is 1100nm?
It lies in infrared region of electromagnetic spectrum.
is the the visible spectrum occupies most of the electromagnetic and sonar spectrum?
The visible spectrum is a tiny, almost negligible slice of the electromagnetic spectrum. 'Sonar' has no place in this discussion. It's not even electromagnetic.
The electromagnetic spectrum includes what?
The electromagnetic spectrum includes electromagnetic waves with a continuous flow of the wavelength.
What is the full range of electromagnetic radiation called?
There are seven types of electromagnetic waves and they are: 1. Radio waves 2. Microwaves 3. Infra-red waves 4. (visible) Light waves 5. Ultra-violet waves 6. X-ray waves 7. Gamma rays
Why is light in the electromagnetic spectrum Is light a type of electromagnetic radiation But how does that work Light is not magnetic or is it?
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.
What electromagnetic spectrum are safe for humans?
in electromagnetic spectrum visible light is safe for humans
What is electrmagnetic spectrum?
Electromagnetic spectrum is a diagram that show the range, or spectrum of electromagnetic waves, in order of wavelength, frequency and energy.
