The electromagnetic nature of light was discovered by Maxwell. James Clerk Maxwell, a Scottish physicist, formulated the theory of electromagnetism in the 19th century. He unified electricity and magnetism into a single set of equations known as Maxwell’s equations, predicting the existence of electromagnetic waves, including light, propagating through space at the speed of light.

The electromagnetic nature of light was discovered by Maxwell (Option [C]). James Clerk Maxwell, a Scottish physicist, formulated Maxwell’s equations in the mid-19th century. These equations unified electricity and magnetism, predicting the existence of electromagnetic waves, including light. Maxwell demonstrated that light is an electromagnetic wave propagating through space at the speed of light, and his work laid the foundation for understanding the fundamental relationship between electricity, magnetism, and light.
Option [A], Snell, is known for Snell’s law of refraction, describing how light bends when passing through different materials. Option [B], Newton, proposed the corpuscular theory of light, suggesting light as a stream of particles. Option [D], Young, conducted experiments demonstrating the wave nature of light through his double-slit experiment, contributing to the understanding of light as waves.
Thus, James Clerk Maxwell is credited with discovering the electromagnetic nature of light, revolutionizing physics with his unified theory of electromagnetism.
