Radio Wave Discovery

The discovery and practical application of long radio waves are primarily credited to Guglielmo Marconi.

• Guglielmo Marconi (1895-1896): He successfully demonstrated wireless telegraphy using radio waves, achieving transmission over increasing distances. His work laid the foundation for practical radio communication, often utilizing what were considered long wavelengths at the time.
• Heinrich Hertz: While Hertz experimentally confirmed the existence of electromagnetic waves (radio waves) predicted by Maxwell's theory in the 1880s, he did not focus on their practical application or long-distance transmission.
• Isaac Newton: Known for his work on laws of motion, gravity, and optics, Newton lived long before the discovery of radio waves.
• W. Rontgen: Wilhelm Conrad Roentgen discovered X-rays in 1895, a different part of the electromagnetic spectrum than radio waves.

Therefore, Marconi is recognized for the development and invention related to the practical use of long radio waves.
