Dr. Heinrich Hertz
Radio waves were first predicted by mathematical work done in 1865 by James Clerk Maxwell. Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations. He then proposed equations that described light waves and radio waves as waves of electromagnetism that travel in space. In 1887, Heinrich Hertz demonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory.
Guglielmo Marconi (Marchese Guglielmo Marconi), an Italian inventor, proved the feasibility of radio communication. He sent and received his first radio signal in Italy in 1895. By 1899, he flashed the first wireless signal across the English Channel, and two years later received the letter "S", telegraphed from England to Newfoundland. This was the first successful trans-Atlantic radiotelegraph. Wikipedia has a good article on this Nobel Prize winner, and a link is provided.
The German Physicist Heinrich Hertz was the first to generate electromagnetic radiation (radio waves) and detect them on the other side of the laboratory. He did that in 1888, when Benjamin Franklin had been dead for 98 years.

Heinrich Hertz demonstrated the photoelectric effect in 1887, showing that light could eject electrons from a material, suggesting light behaves like particles. Albert Einstein built on this in 1905, proposing the idea of light quanta or photons - packets of energy that behave like particles, explaining the photoelectric effect.

The unit for measuring radio waves, the hertz (Hz), is named after German physicist Heinrich Hertz, who made significant contributions to the study of electromagnetism and radio waves in the late 19th century.

The unit hertz was named after the German physicist Heinrich Hertz, known for his pioneering work in the field of electromagnetism.
Heinrich Hertz discovered radio waves in 1887 while conducting experiments to prove the existence of electromagnetic waves predicted by James Clerk Maxwell's theory. His work laid the foundation for the development of wireless technology.
The hertz is named after Heinrich Rudolf Hertz who proved that electromagnetic waves did exist. The measurement of one gigahertz is the equivalent of 1,000,000,000 hertz.
Heinrich Hertz was a German physicist known for proving the existence of electromagnetic waves, which laid the foundation for the development of radio technology. His experiments demonstrated the transmission of electromagnetic waves through space and their similarity to light waves. Hertz's work led to the development of wireless communication technologies.
The unit "hertz" is named after Heinrich Hertz, a German physicist who was the first to conclusively prove the existence of electromagnetic waves. He made significant contributions to the field of electromagnetism and laid the foundation for the development of modern communication technologies.
Heinrich Hertz proved the existence of electromagnetic waves. The unit of frequency, hertz (Hz), is named in his honor.
