Who invented radio history?
inventor Guglielmo Marconi

Why is the radio important in history?

During the war, the military used it almost exclusively and it became an invaluable tool in sending and receiving messages to the armed forces in real time, without the need for a physical messenger.
Why was radio created?
Radio primarily owes its evolution to the invention of both the telephony and the telegraph. All of these technologies are more closely related than you might think. Radio started life as “wireless telegraphy,” and it was designed for communication, rather than music and entertainment.
What are 3 facts about radio waves?
Despite their versatility, radio waves have lower frequencies than those of microwaves.
- Their signals are bounced through the atmosphere. Actually, radio waves are shot straight into a part of the atmosphere called the ionosphere.
- Radio waves bounce forever if not absorbed.
- Radio waves can travel forever.
What was a radio first called?

How did radio get its name?
Who founded radio waves?
Heinrich Hertz proved the existence of radio waves in the late 1880s. He used a spark gap attached to an induction coil and a separate spark gap on a receiving antenna. When waves created by the sparks of the coil transmitter were picked up by the receiving antenna, sparks would jump its gap as well.
