Invention of the Radio..
About 180 years ago, Francesco Zantedeschi was the first person who tried doing an experiment by connection between light, electricity, and magnetism. But during 1864, James Clerk Maxwell had a theory and predicted that electromagnetic waves do exist, which include radio waves. This will then help inventors to invent radio. But in 1901, a guy named Marconi says that he received daytime transatlantic radio frequency signals at a wavelength of 366 metres which he later receive the 1909 (Nobel Prize in Physics) with another guy called, Karl Ferinand Braun for the contribution to the existing radio sciences. That is why the radio was being invented. (:

The radio is a very important invention as it helps the world to communicate. We are able to get information from the radio station, entertainment and even knowledge. It's a very powerful tool for people to get their ideas across.
