The questions below are based on the following text:
Radio owes its development to the invention of the telegraph and the telephone; indeed, all three technologies are closely related, and radio technology actually began as wireless telegraphy. Technically speaking, the term 'radio' refers to either the electronic appliance itself or to the content of the electronic device.
The whole thing started with the discovery of radio waves: these are electromagnetic waves that have the capacity to transmit data such as music, speech and pictures through space. Of those devices that function by using electromagnetic waves, some of the commonest ones are the following: radio, microwaves, cordless phones, remotely controlled machines and television.
During the 1860s, James Clerk Maxwell predicted the existence of radio waves; in 1886, the German physicist, Heinrich Hertz demonstrated that rapidly varying electric currents could be projected into space in the form of radio waves: waves that are similar to those of light and heat. In 1866, Mahlon Loomis successfully demonstrated the concept of wireless telegraphy: his experiment provided the first known example of wireless aerial communication. Finally, Guillermo Marconi proved that communicating by radio waves was technologically feasible: in 1902, a transmission from the Marconi station in Glace Bay, Canada, became the first radio message to cross the Atlantic. Guillermo Marconi is often called the "Father of Radio"; however, he did not invent it. Be that as it may, he was probably the person who did more than anyone else to advance radio technology.
