The invention of radio by Popov is a controversial issue that remains open

With the opening of electricity opportunitiesmankind have significantly expanded. People have learned to transmit by wire signals that carry information and even human speech. But the use of such a connection had some inconvenience. The wires could not be pulled after the moving transport. The invention of radio Popov became a new stage in the development of communication.

It allowed the transfer of information from one radio receiver to another using electromagnetic waves. One source emits radio waves, and the other receives them.

The invention of Radio Popov took place in 1895. It was then that he created the first radio set. This device was very sensitive to radiation of electromagnetic waves. Initially, the receiver received and reacted only to those that appeared in the atmosphere, that is, to lightning discharges. But gradually it was improved and began to distinguish information transmitted from other sources. But the year of invention of the radio is 1895th.

On the responsible task of creating a radio receiverMany scientists from all over the world were fighting. These studies began long before the implementation of the plan. The history of the invention of the radio includes several stages and a very long period of time. The Danish scientist Oersted carried out research and found out that a field of magnetic waves appears near the apparatus conducting the current. Another physicist Faraday discovered and proved in practice that a magnetic field is the source of the birth of an electric current. Several other scientists have determined the relationship between magnetic fields and the electric field and their effect on each other.

Therefore, we can say that the invention of radio Popov, was the final stage of the work, which was done by many people.

Technical device of the first receiverelectromagnetic waves was very simple. He had an electric bell, a battery, a tube of glass, in which were sawdust and an electromagnetic relay. As a transmitter, a spark spark gap was used, which provoked wave oscillations in the antenna. The antenna was also used for the first time. The incoming waves acted on sawdust, which became conductors of electric current. The relay weakened their action, and they took another signal.

But on this development and improvementapparatus did not end. Popov created a radio receiver that was able to work and receive waves at farther distances. Within five years the range of reception was 40 kilometers.

Radio has become an integral part of people's lives. Thanks to him, it was possible to save the fishermen, who were carried away to the sea on an ice floe in 1900. People appreciated the convenience of such a connection.

But the invention of radio Popov stillis questioned. The debate over whether he really was the first to invent this device does not subside to this day. In the west, it is believed that the first inventor of the radio was Marconi.

Both inventors did practically the same thingstechnical additions to existing inventions. It happened at the same time. When Popov demonstrated his radio, Marconi did the same, and even applied for a patent. Therefore, this issue remains open.

In Russia, the official radio day is May 7, 1895. The inventor of the radio is Alexander Popov.

But most importantly, despite all the arguments, thisthe event gave impetus to the development of communication. It opened up new opportunities and prospects for mankind in this field. Today we can not imagine life without radio and other communication. Therefore, humanity should be grateful to those scientists who for many years went to this discovery. Each of them contributed to the common cause for the benefit of all people.
