Maxwell equations is the set of four partial differential equations that describe the properties of electric and magnetic fields and their relationship with their sources, the electric charge and electric current, according to the theory of classical electrodynamics. These four equations are used to show that light is an electromagnetic wave. Separately, four equations are respectively referred to as Gauss's law, Gauss law for magnetism, Faraday's law of induction and Ampere's Law. The fourth equation is the Lorentz law is a complete set of laws of classical electrodynamics.
Maxwell's correction to Ampere's Law is quite important: thus, this law states that electric fields can cause changes in the magnetic field, and vice versa. Thus, although there is no electric charge or electric current, still have a wave oscillation dimungkinkann create a magnetic field and electric field are stable and can spread continuously. Maxwell's fourth equation describes quantitatively this wave, and further predicted that these waves must keep close track has a certain universal rate. This rate can be calculated simply from the two constants of physics that can be measured (constant electric and magnetic constants) Rate calculated for exactly the same electromagnetic radiation with the speed of light. Light is a form of electromagnetic radiation (like X-rays, radio waves and others). Thus, Maxwell combines two previously separate fields, electromagnetism and optics.Undo edits
