Earth does not emit light because if it did we would be a star, comit, or our own sun, and we would be made of hydrogen and helium like other stars and comits. i am no expert but my studies show the previous information.

You are right that only stars can emit light, but a comet (not "comit") is just like an asteroid or planet in being visible only because it reflects the light from the star it orbits.

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.
Is the light wave electromagnetic or no?
The light wave is electromagnetic yes.
Why call light as E M wave which is not having neither electric nor magnet?
Electromagnetic waves, like light, do involve changes in the electric and the magnetic field. These changes propagate at the speed of light - as a wave.Electromagnetic waves, like light, do involve changes in the electric and the magnetic field.

Energy that travels at speed of light?
That can be light, or some other electromagnetic wave (light is an electromagnetic wave), or gravitational waves.
How is visible light and electromagnetic radiation different?
They are not different.Visible light IS electromagnetic radiation.
Why Speed Of Light is not affected by Earth's Magnetic Field although Light is considered to be an Electromagnetic wave?
As light can also travel in vacuum so no extra force can change its direction.
Can fiber optic cable be installed near medium voltage cables?
Since light can't be affected from any electromagnetic field, then sure!
What radiation is the light bulb?
Light, heat, and a very small amount of electromagnetic field.

How long does earths magnetic flip take?
An electromagnetic wave is a form of radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge. An electromagnetic wave travels like any other form of radiation or light, except for the fact that an electromagnetic wave moves perpendicular to an electric field and a magnetic field.
Why is light called electromagnetic radiation?
Light is known as electromagnetic radiation because it has two complementary components which were found to be a magnetic field wave in synchronous motion with an electric field wave.
What is electromagnative field?
Nothing I know of but an "electromagnetic field" is a field with one axis the electrical one and another axis the magnetic one and a third axis of spacetime. Light is an electromagnetic field phenomenon.
Does light propagate around electromagnetic fields in a vacuum?
It is not very clear what the question means. Light is an electromagnetic field and it can propagate in a vacuum. Propagation of a beam of light is unaffected by any other electromagnetic fields in its path.
What type of electricity is lighting?
Light is an oscillation of the electromagnetic (photon) field.
Why radiation waves does not need any medium?
they do. As you might be aware of, light( radiation wave) is made of electromagnetic wave and its medium is electromagnetic field. So basically the medium of radiation waves is electromagnetic field.
Which wave represents visible light?
Visible light is a type of electromagnetic wave.
What two things shot from the sun strike the earths atmosphere?
Electromagnetic waves (including light); solar wind.
