- Electromagnetism : Phenomena and theories regarding electricity and magnetism.
- Vacuum (science) : A realizable vacuum with a gaseous pressure that is much less than atmospheric.
- Coulomb's law : An inverse-square distance law, like Newton's gravitational law, describing the forces acting between electric point charges; also valid for the force between magnetic poles.
- Electric constant : A physical constant in the International System of Units (SI) relating capacitance to area in classical vacuum with an exact value ε0 = 107/(4πc02) F/m, c0 being the defined value for the speed of light in classical vacuum in the SI units.
- Electromagnetic wave : A change, periodic in space and time, of an electric field E(r,t) and a magnetic field B(r,t); a stream of electromagnetic waves, referred to as electromagnetic radiation, can be seen as a stream of massless elementary particles, named photons.
- Heisenberg Uncertainty Principle : The quantum-mechanical principle that states that certain pairs of physical properties cannot simultaneously be measured to arbitrary precision.
- Maxwell equations : Mathematical equations describing the interrelationship between electric and magnetic fields; dependence of the fields on electric charge- and current- densities.
- Speed of light : A physical constant c describing the speed of electromagnetic radiation in vacuum. In the International System of Units the metre is the distance light travels in classical vacuum in 1/c seconds, using the defined value c = c0 ≡ 299 792 458 m/s (exact).
