What is Radio and its complete information ?
If you want to know about Radio, then stay on this post as usual. Today we will give you information about what is Radio ?
You might know all about Radio but do you also know what is Radio ? How many types are there? And how to use it?
In India, both smart phones and the Internet have become very cheap for a few years. But because of these, the trend of social media and platforms like that has increased, but the importance of instruments like radio, television has been lost.
The use of television is still not reduced, but the use of radio has reduced very little. In this time, radio is used by either very old persons or people who are fond of radio.
At this time there was no shortage of internet resources, but in the beginning of radio technology, only a few people used to do it. But when this technology became cheaper, radio also started to be available to the general class as well.
In the time of radio technology, radio was mostly used for broadcasting news. But after this, it started being used in entertainment also.
what is radio ?
Radio we are also known as Radiologic Technologists, Medical Radiation Technologists and Diagnostic Radiographers.
These are health care professionals who specialize in imaging human anatomy for the treatment and diagnosis of pathology. Radiographers are often referred to as X-ray technicians.
How we hear the name of radio, then the picture of FM appears in our brain. But it is actually a machine.
Radio is a technique in which messages are sent from one place to another without a wire. In this time all the equipment of all is based on radio technology.
If radio is understood in simple language then it is a technology in which signals are sent through radio waves.
With the help of radio technology, we can send massages through radio stations to many people through radio waves.
Radio waves are a kind of electromagnetic waves that have a frequency of 30 Hz to 3000 Ghz.
The radio wave is generated by a transmitter, which is connected to an antenna. A radio receiver device is used to receive these waves, which consists of an antenna.
Radio was invented by-
The development and innovation of technology like radio made our life very easy. The industry defense system in the country made its innovation even more important by using radio technology.
The inventor of the radio is “Guglielmo Markoni“.
Guglielmo Markoni has been considered the main inventor of the technology of radio invention.
In the 1880s, Rudolf Hertz discovered the ‘electromagnetic waves’. Gülielmo Marconi was the first person who built a successful long-range device using radio technology.
For this reason, he is considered the inventor of radio technology. At that time, instruments were being made by many scientists and experts based on the study of electromagnetic waves.
But Guglielmo Markoni was the only person who produced the first successful device.
During a demonstration, a scientist showed off a peg by electromagnetic waves. It was very surprising at that time. This event precedes Merconi’s invention of radio technology.
A few days after this incident, radio was invented by Marconi. Marconi invented radio technology in the 1890s.
Radio was invented in 1896, according to US patent records, ‘Gülielmo Marconi’.
History of Radio –
The invention of radio is considered to be one of the most important inventions in the world. Modern radio technical systems cannot be given to a scientist.
The history of radio invention is quite visible. James Clerk Maxwell was the invention of radio by a British scientist.
These scientists used to research electromagnetic waves everyday. But he did not give the correct theory of electromagnetic waves.
A British scientist specialized in Oliver Heaviside who carried out the discovery of electromagnetic waves. But they also did not present the exact form of electromagnetic waves.
A scientist named Heinrich Rudolf Hertz made the breakthrough discovery of electromagnetic waves. He succeeded in finding the main questions related to electromagnetic waves.
After this, scientists like Jagdish Chandra and Oliver Lodge advanced the discovery of electromagnetic waves.
Guglielmo Marconi finally invented radio in 1896. This invention was initially used for armies.
Useful start of radio:
The first broadcast of radio in India was started in Mumbai in 1920. Radio clubs were formed in Mumbai for this.
The big program was also broadcast from the Radio Club in Mumbai, India. In 1927, service transmission with 2 transmitters was established on a privately owned basis in Kolkata and Mumbai.
The Government of India took the transmitters under its control in 1930 and started broadcasting ‘Indian Broadcasting Service’. The name of which was later changed to ‘All India Radio’.
After the independence of India, the importance of radio was also big and radio reached every household.
