Who is the father of radio? Who invented radio?

The inventor of radio communication was the young Italian inventor Marconi.

Radio waves refer to electromagnetic waves in the radio frequency band that propagate in free space, including air and vacuum. The shorter the wavelength and higher the frequency of a radio wave, the more information is transmitted in the same amount of time.

Radio waves propagate in space in the following ways: direct, reflected, refractive, penetrating, diffracting (diffraction), and scattering.

In 1894, Marconi's experiment was already making a breakthrough, not only successfully repeating Hertz's experiment, but also achieving transmission at a distance of only a few centimeters.

Two years later, Marconi filed a commercial patent for his radio in England under patent number 12039. The following year, he established Wireless Telegraph and Signal****, which was later renamed Marconi Company.

For this invention, Marconi became the winner of the Nobel Prize in Physics in 1909.

Principles of radio technology:

Radio is a kind of electromagnetic wave that propagates freely in space, radio technology takes the radio wave generated when the current in the conductor changes in strength as the carrier, the information modulation is applied in it, the electromagnetic wave carrying the information is transmitted in space, and reaches the radio broadcasting terminal equipment, the radio wave changes in the magnetic field at this time, because there is a current in the conductor, the data information needs to be extracted by demodulation.

Radio waves contain a magnetic field that vibrates rapidly. The speed of the vibration is the frequency of the wave, measured in hertz (Hz). 1 hertz is equal to one vibration per second. One kilohertz (khz) is equal to 1000 hertz. Different frequency bands are used to transmit a variety of different information.

There are two theories about this. One says that radio was invented by Galilmore Marconi, and the other is that it was Nikola Tesla. However, it is generally considered to be the former.

The first radio communication device was invented by Tesla and was displayed in front of the public and patented, but for various reasons, the device was not put into practical use. Later, Marconi improved and put the device into practical use, and the U.S. Patent Office revoked Tesla's patent and sublicensed it to Marconi.

In 1943, shortly after Tesla's death. In order to avoid paying royalties to Marconi, who is still alive, the United States reaffirmed that Tesla's patent was valid. Until now, the patent for the radio has belonged to Tesla in principle.

However, it is widely believed in the academic community that the inventor of the radio was Marconi, so it is good to know, and if it is a question or something, it is better to fill in Marconi honestly.

In 1893, Nikola Tesla made his first public demonstration of radio communication in St. Louis, Missouri, USA. In his presentations for the Franklin College of Philadelphia and the National Electric Light Association, he described and demonstrated the basic principles of radio communications. The instrument he made contained all the essential elements of the radio system before the invention of the tube.

Guglielmo Marconi holds what is often considered to be the world's first patent for radio technology, British Patent 12039, "Improvement of electrical impulses and signal transmission technology and equipment required".

Nikola Tesla obtained a patent for radio technology in the United States in 1897. However, the U.S. Patent Office revoked his patent in 1904 and granted Marconi a patent for the invention of the radio instead. This move may have been the result of the influence of Marconi in the United States, including Thomas Edison and Andrew Carnegie.

In 1909, Marconi and Karl Ferdinand Braun were awarded the Nobel Prize in Physics for their "contribution to the invention of wireless telegraphy".

In 1943, shortly after Tesla's death, the U.S. Supreme Court reaffirmed Tesla's patents. This decision recognized that his invention had been completed before Marconi's patent. Some believe that this decision was made for obvious economic reasons.

In this way, the United States** in World War II could avoid paying Marconi royalties.

In 1898, Marconi opened the world's first radio factory on Hall Street in Chelmsford, England, employing about 50 people.

Radio has gone through various stages of development from electron tubes to transistors, to integrated circuits, from shortwave to ultra-shortwave, to microwave, from analog to digital, from fixed use to mobile use, and radio technology has become an important pillar of the modern information society.

Which scientist has been called the "father of trembling Zen wires"?

a.Marconi.

b.Tesla.

Correct Answer: a

Galilmo Marconi was born into a wealthy Italian family. While studying at the University of Bologna, he successfully conducted radio communication experiments with electromagnetic waves at a distance of about 2 kilometers. In 1909, he won the Nobel Prize in Physics with Bernburn and is known as the "father of radio".

In 1943, the U.S. Supreme Court reversed Marconi's decision and ruled that Tesla was the inventor of the radio.
