Some people say radio was invented by Guglielmo [gu-lee-YER-mo) Marconi of Italy. Marconi sent the first radio communication signals through the air in eighteen ninety-five. In fact, no one person can be called the inventor of radio. Many...
Where did Guglielmo Marconi invent the radio? In 1895, he began to experiment at his father's home in Pontecchio, where he was soon able to send signals over one and a half miles. Marconi traveled toEnglandin 1896 to seek a patent for his apparatus. One was granted to him that year ...

In 1895, a young Italian named Guglielmo Marconi invented the first radio and sent a message over one kilometre away. In 1897, he started a company and developed several uses for radio. A radio broadcast works by changing sounds or signals(信号) into radio waves, and then the radio ...
Radio broadcasting is a way of sending out sound signals using radio waves. It was invented over 120 years ago and is still used today (well, you must know that… you listen to Fun Kids!). Radio waves are a type of energy that can travel through the air and carry sound with them. ...
Marcont shared the Nobel Prive in Physics with Ferdinand Braun for their development of wireless telegraphy(九线电报) A radio broadcast works by changing sounds or signals into radio waves, which travel through air and space from a radio station. The radio receiver changes them back into the ...

During the early 1920s attempts were made to transmit radio signals over long distances by bouncing them off the layers of charged particles in the Earth’s ionosphere. The success of these experiments prompted the establishment of worldwide shortwave communication by the late 1930s. Shortwave ...
Guglielmo Marconi was key in proving radio communication's feasibility by sending the first wireless signals. The invention of AM radio and FM radio allowed for better and clearer radio broadcasts worldwide. Radio owes its development to two other inventions: thetelegraphand thetelephone. All three...
