Answer:
About 150 years ago, James Clerk Maxwell, an English scientist, developed a scientific theory to explain electromagnetic waves. Electromagnetic theory is described by Maxwell's equations. The first hint that light is electromagnetic radiation came from electromagnetic experiments not involving visible light. ... From relativity theory we know that the speed of light is a fundamental constant and the ultimate limit of speed.
Michael Faraday is probably best known for his discovery of electromagnetic induction, his contributions to electrical engineering and electrochemistry or due to the fact that he was responsible for introducing the concept of field in physics to describe electromagnetic interaction.
