Guglielmo Marconi and Radio Waves

Guglielmo Marconi was a young man fascinated with the recently discovered phenomenon of electricity. Telegraph wires were already being used to send messages with electricitythere was even a cable under the Atlantic Ocean making communication between continents possible. But when Marconi learned about the discovery of electromagnetic waves, he thought that they could be used to send messages without wires. In 1894, when he was 20 years old, Marconi began experiments in sending messages: first a few feet, next a few yards, then over a mile, and at last across the Atlantic Ocean.

Marconi s wireless telegraphy made it possible, for the first time, for ships at sea to communicate with the land and with each other. Marconi s work provided the foundation for the amazing developments in electronic technology that occurred in the twentieth centuryradio, television, radar, sonar, microwave ovensand are still occurring at dizzying speed.
