Empirically speaking, it is the Hubble Limit. According to established theory, it is indefinite.
I'm leaning toward the Hubble Limit being the right answer
The electromagnetic spectrum is not bounded to a finite number of frequencies.
0 kHz to 300 GHz
The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.
The four known basic forces in the universe are the gravitational force, the electromagnetic force, the strong force, and the weak force.
The strongest electromagnetic force on Earth is found between the North and the South Poles. The source of the force is found in the core of the Earth, which is rotating slightly faster than the Earth's own rotation, creating a generator of immense proportions.
You can't see any force. You can only see light which is a ripple in the electromagnetic field.
This is essentially correct. As we currently understand it, there are four basic forces in the universe. These are gravity, the strong and weak nuclear forces (strong and weak nuclear interactions), and the electromagnetic force. An electromagnetic wave is an expression of the electromagnetic force, and it is pure energy. There is no matter associated with electromagnetic waves. It might (or might not) be helpful to note that electromagnetic energy can be converted into matter, and we see this happen in an event we call pair production. A link is provided below to a related question for the curious investigator to use.
Electromagnetic force is greater because in microscopic theories usually gravitational force is neglected and we can attract a pin from the ground by electro magnet easily yet smaller in size, both acts at the vast range but electromagnetic force is far more greater then gravitational.
The electromagnetic force has a longer range of effect than any other force except gravity. It is also the second strongest force. Unlike gravity, it can be both attractive and repulsive.
The Weak Force is stronger than the Electromagnetic Force at the range of an atom, and therefore they do not collide.

Motion. Physics. Electromagnetic force; gravitational force. eh?
The four forces are:gravity - very long range and always attractiveelectromagnetic - long rangeweak nuclear force - very short range, limited to atomic nucleusstrong nuclear force - very short range, limited to atomic nucleus
electrostatic force is the force between the two opposite charges where as the electromagnetic force is movement of electrons
The strong nuclear force is responsible ofmaintainingprotons and neutrons within the nucleus (its range is short) while the electromagnetic force is responsible of maintaining the electrons around the nucleus.
The electromagnetic spectrum.
the electromagnetic spectrum
This is the Electromagnetic force. (Technically, it's the Lorentz force, which is the force on a charge due to an electromagnetic field, but either will do.)
Well one way to look at it is that a photon IS an electromagnetic field. The photon is the gauge particle for the electromagnetic force. Without photons there would be no electromagnetic interaction force, and therefore no electromagnetic fields.
