Radio is the medium of communication. This is a wireless set. Radio can transmit messages all over the world, and the message can be obtained in any part of the world.
A German scientist Hertz first produced an electro-magnetic waves using a simple device. However, the waves they made could not travel long distances. Later in 1885, an Italian scientist invented electro-magnetic waves, called Marconi, which could travel long distances carrying messages. These electro-magnetic waves travel at a speed of 3 lakh kilometers per second and cover the earth's surface in just one second. Electro-magnetic waves with a frequency range of 100 kg hertz and 100000000 kg of hetz are called radio waves. We can see them in short waves and medium wave transmission in their waves. Marconi received Nobel Prize for Physics for his invention in March 1909.
Radio works on a principle. The sound waves produced by the speaker are converted into electro-magnetic waves by the microphone. Electro-magnetic waves are susceptible to the carrier wave by the radio transmitter on the required wave length. Radio transmitter has an important role in the radio transmitter.
The radio wave transmission is either influenced by (1) ground waves or surface wave or (2) sky waves or ionosphere waves. Waves of the ground or surface waves are not effective for long distances, because they lose energy by obstruction of hills and trees. Second, the electromagnetic waves of the sky type are formed in the atmosphere, from which they return to Earth. There is no obstacle in these waves. The ionosphere is an atmospheric area between 180 kilometers and 400 kilometers above the earth. Thus reflected waves are received from the radio receiver's airport. It changes them back to sound waves to produce original sound waves and goes to the amplifiers. Thus men can hear long distance speech, message, etc. through radio in a single second.
Radio is no longer a luxury. This has become a necessity. Even remote villages, we find radio. Shepherds and cobbler take the radio with them. Radio is available in different sizes. Radio is not limited to news communication only. It is now a medium for many things. Radio is mandatory in flight planes and sailing ships.

To get knowledge and entertainment, uneducated can easily use this media.
Radio in India is largely controlled by the state. Akash Vani, which is called it, is a controlled organization. Amateur radio sets called HAM have come in and they are doing some useful service in times of natural calamities.

Radio is playing a very useful role in the field of communication and it will continue to do so.

Man has always been entertained by himself. He went on to discover new things for peace of mind. Scientists have started competing in new inventions. Humans made Nature their toy. Today everything in electricity at home is a miracle of scientific inventions.
Radio is also one of those inventions. Both Marconi of Italy and Jagdish Chandra Basu of India tried to send sound waves from one place to another. Marconi was successful in 1901 when he sent a newsletter from England to New Zealand.
In 1859, Jagdish Chandra Basu made this effort on a small scale. The Sultry India could not give this place an important place for them, and they remained behind in this scientific race and Marconi became immortal. India's first radio station was established in 1927 and today there are several radio stations in each province. How does radio noise reach us? It is a process - firstly the AIR Center converts sound into electricity waves by electricity.
Then these waves are left in the sky. These waves catch the radio receiver and can listen to the program by pressing the button of the listening radio. There are many types of radio, but primarily we can classify them into three parts - local, all-Indians and related to abroad.
On local radio only programs of provincial special programs, All India Radio are broadcast programs from India and foreign radio programs overseas. There is a needle inside the radio, which is rotated around with the help of a button. So that the contact with the center gets added and the sound starts coming up.
Radio has many benefits. The latest news of country and abroad is known at home. Cricket is in England and the eyes are seen alternately in Hindi and English. Apart from this, information about old new songs, talks with artists, classical music, drama, important talks, women's domestic events, in which they are given information about the methods of cooking-food, clothing care, home remedies etc.

Metropolitan, city, tax, village all-round experiment continues. There has not been any reduction in its popularity so far. Radio or Achaarani was invented by a scientist named Marconi of Italy. Through this experiment, Marconi was inspired by the waves generated by throwing a piece of stone into the tranquil waters. Checked and certified that waves like that happen in the sounds 'emanating from the mouth of humans'. They are transmitted in the atmosphere or in the same plane as the waves formed in the ocean-water.
So he made many types of electrical equipment and kept trying to catch those sound tones. The result of that effort was astonishing to everyone in the end as an All India Radio. An important discovery of science, an ever-changing invention became. Nowadays called AIR Broadcasting Center or Radio Station, there are many types of sound magnifier reserved in the center. There are dances, music, instrumental instruments, news, drama and so on etc. In the first place space is given an opportunity to expand its overall and skillful expansion or expansion. After that, by holding a spread of those waves of sound through a machine, Then they are transmitted by radio or AIR and transmitted to the far-reaching audience as if they were spoken or hyped.
The first center to bring this invention of Marconi to the masses was established in England in 1921. This invention has surprised and amazed the world by broadcasting and transmitting news from England to New Zealand for the first time. After this primary success, more work has been done on this. With the sustained effort and successful development of many other scientists, this advanced-developed form of All India came out that today in the whole world, successful use is being done in many different forms.
Akashvani is being used in many ways, due to which its importance is also very high. It has become a means of making bread and butter for thousands of millions of artists, technicians, manufacturers, vendors and office-bearers.

By doing so, he instantly provides the international dimension of every person's information. During the night especially at the time of the day and its foreign service by introducing India to the international world by its programs, he mixes them with us in a way. Akash also keeps on increasing our knowledge in many other ways.
New information from new information, information about agriculture works and weather, talks on national-international topics and history, information and broadcasting of literary activities, art literature. Reviews, even. This type of transmission of subjects for the examinations is done for the students. While spreading dance, song, music, film music, film stories, poetry and broadcasting of Musashirs, post-production, choreography, Akashvani also presents the rich content of entertainment for us.
There are as many other forms of entertainment as entertainment, drama, radio-metaphor, glance, jokes, etc. It can be found to be very entertaining by listening often. In this way, the suppression of knowledge and entertainment-Pipasa happens together. The publication is also a good tool for business information.
On this, advertisements of different types of products are broadcasted. Timetables, market-expressions of lost-foundations, railways and aircraft etc. are also reported. In this way, AIR can be called 'Pandora's box', which is open to all kinds of pigeons, other colorful birds, and also to the boundaries of our knowledge-science Provide reasonably detail and new dimensions. In the light of these facts, the obvious significance of AIR can be highlighted.
