Maxwell's equations were first postulated by James Clerk Maxwell in 1865. They describe the behavior of electrical and magnetic fields, and have been instrumental in many scientific discoveries.
Maxwell's equations are also used to calculate the speed of light in a vacuum. To get more details about the mit maxwell equation you may check it here.

Electromagnetic waves travel with a speed that is a function only of the square root of their frequency. Electromagnetic radiation can be polarized in a direction perpendicular to its transverse wave direction. In addition, the total energy emitted by an electromagnetic wave is proportional to its intensity.
Maxwell's equations can be used to calculate the speed of light in a vacuum, but it is impossible to calculate the frequency of electromagnetic radiation because the energy of a photon has non-zero rest mass.
Maxwell's equations are named after James Clerk Maxwell (1831-1879), who published them in 1865 and received his doctorate from Cambridge University in 1855. The equations relate electric and magnetic fields, which form an essential component of all electrical circuits.
As such, they have led to many scientific discoveries and are still used every day to help us communicate, power our computers and other appliances, and provide entertainment such as radio and television. Maxwell's equations describe not only electric and magnetic fields in circuits but also fields with electric and magnetic fields.
In fact, the equations describe all three fields together in a common mathematical framework. The field with electric and magnetic fields is called electromagnetism (or EM) while the field with electric and no magnetic field is called electrodynamics (or E).
