Guglielmo Marconi based his work on which physicist's theory?

• A. James Clerk Maxwell
• B. Heinrich Hertz
• C. Nikola Tesla
• D. Edwin Armstrong

Answer: (A)

Marconi’s work rests on James Clerk Maxwell’s theory. Maxwell showed that changing electric and magnetic fields form electromagnetic waves that propagate through space, and that these waves travel at the speed of light. This theoretical framework predicted radio waves could carry signals, giving Marconi the foundation to develop wireless communication. While Heinrich Hertz later demonstrated the existence of radio waves in experiments, and Nikola Tesla and Edwin Armstrong contributed important ideas and technologies, Maxwell’s equations provide the essential theory that made Marconi’s practical work possible.
