Electromagnetic wave theory was proposed by:
Correct answer: E. Maxwell
- A. Huygen
- B. Fraunhofer
- C. Fresnel
- D. Coulomb
- E. Maxwell
Explanation
James Clerk Maxwell is credited with formulating the electromagnetic wave theory in 1864. He proposed that light is a form of electromagnetic radiation, which was a groundbreaking unification of previously separate fields: electricity, magnetism, and optics. His set of equations, known as Maxwell's equations, describe how electric and magnetic fields interact and propagate as waves through space.Other options are incorrect as they contributed to different aspects of physics: Huygens with wave theory of light, Fraunhofer with spectral lines in light, Fresnel with wave optics, and Coulomb with electrostatics.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
