WebMay 27, 2016 · Since classical electromagnetism doesn't have any other fields transforming in a representation of the gauge group, but just the current j μ with d ⋆ j = 0 that transforms trivially, you can't decide, classically, which one to choose. We take U ( 1) because this is what get in the quantum theory. – ACuriousMind ♦ May 27, 2016 at 15:04 1 WebAn accurate theory of electromagnetism, known as classical electromagnetism, was developed by various physicists over the course of the 19th century, culminating in the work of James Clerk Maxwell, who unified the preceding developments into a single theory and discovered the electromagnetic nature of light.
WebAug 13, 2024 · Classical theory of light is a wave picture. Both amplitude and frequency are the two factors that affect the energy transferred by a wave: the height of the wave, and the number of waves passed by each second. The amplitude tells you … Webe. Maxwell's equations, or Maxwell–Heaviside equations, are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical …
