When were radio stations first licensed in Australia?
Radio is a way of transmitting signals without wires. It uses electromagnetic radiation to transmit sounds made in one place to listeners in many places. Radio is also known as 'wireless telegraphy', or 'wireless', as earlier methods for sending signals (such as the telegraph and telephone) used wires. Australia adopted radio for communications at sea and in lighthouses, and wireless telegraphy gradually replaced the Overland Telegraph which had been completed in 1872.
Where did Marconi make the first radio?
Actually, he didn't make a radio. He made the technology of radio possible, however. Guglielmo (William) Marconi did experiments with radio waves and proved you could send messages through the air (which was called the "ether" back then) without any wires. While Marconi was from Italy, he did most of his experiments in England. Back in the late 1800s, you could only send long distances messages by telegraph, and it needed wires spread across the country. As a result, to send messages overseas was difficult, and inventors were trying to find a way to send messages without a need for telegraph wires. Marconi was one of the first to achieve this; another was an inventor named Nikola Tesla. I enclose an interesting link about the debate over whether Marconi or Tesla really invented what became radio.
