Radio - A brief information and history
With the help of a radio, it is possible for people to convey their messages from one place to the other without any problems or issues. This is done with the help of the radio waves which allow the messages to be released into free space and thus even though they could not be heard or seen by human beings, if a radio is available within the room of the person, these signals and messages could easily be picked up through it. It was in the year 1900 that the human voice was successfully transferred through radio in a wireless form by Roberto Landell de Moura of Brazil. Since then, there have been various other changes that have taken place, allowing radio to be one of the most popular modes of communication even today, after almost a century has been passed since its invention.
