Timeline of electromagnetism and classical optics lists, within the history of electromagnetism, the associated theories, technology, and events.
The history of electromagnetic theory begins with ancient measures to understand atmospheric ... Timeline of electromagnetism, Timeline of luminiferous aether.
1867: James Clerk Maxwell (1831–1879) develops a theory predicting the existence of electromagnetic waves and establishes Maxwell's equations to describe their properties. Together with the Lorentz force law, these equations form the foundation for classical electrodynamics, optics, and electric circuits.
James Clerk Maxwell FRS FRSE (13 June 1831 – 5 November 1879) was a Scottish physicist and mathematician [1] who was responsible for the classical theory of electromagnetic radiation, which was the first theory to describe electricity, magnetism and light as different manifestations of the same phenomenon.
Examples of the dynamic fields of electromagnetic radiation (in order of increasing frequency): radio waves, microwaves, light (infrared, visible light and ultraviolet), x-rays and gamma rays. In the field of particle physics this electromagnetic radiation is the manifestation of the electromagnetic interaction between charged particles.
This timeline lists significant discoveries in physics and the laws of nature, including experimental discoveries, theoretical proposals that were confirmed experimentally, and theories that have significantly influenced current thinking in modern physics. Such discoveries are often a multi-step, multi-person process.
1861–1865 – James Clerk Maxwell summarizes the fundamental equations of electromagnetism into an early version of Maxwell's equations and relates electromagnetism to light in his publications On Physical Lines of Force and A Dynamical Theory of the Electromagnetic Field. [37]
(4) The electromagnetic field is that part of space which contains and surrounds bodies in electric or magnetic conditions In A Treatise on Electricity and Magnetism of 1873, he writes "the electric field is the portion of space in the neighbourhood of electrified bodies, considered with reference to electric phenomena."
