It would be an injustice to attribute this invention to a single man, since he
Max-
The names of many researchers are attached, among others Max
well, who in 1864 mathematically demonstrated the electromagnetic theory
of light, establishing the principle that it propagates through
of waves.
Later, in 1887, the German professor Hertz tested Max-
well discovering and studying those that bear the name of (con-
Hertzian days).
These waves travel through space in all directions with the velocity
power of light (300,000 km per second) No need for cables or wires
driver. They skirt around obstacles and go everywhere. They can pr0-
produced and transmitted with various lengths and frequencies. Experiments and
studies of them were followed by researchers Lodge, Branley and
Marconi until reaching the construction of the radio apparatus that he knows
Known-
we today.
For the operation of the radio device you need the station
station or radio broadcaster that transforms the original sound waves-voice or
music produced before a microphone on electric waves, which are broadcast

radially in space. The waves emitted from the station are very de-
threads when they arrive at our houses, but our receiving apparatus
nlia, making the waves sound again, allowing us to hear the music or voice
that is producing them.
The first broadcasting station of industrial and commercial value was
established in Pittsburgh, in 1920. Soon, the stations, were broadcast
throughout the world and today constitute the fastest means of communication
tion between all continents.
Nowadays, radio programs are very varied and include
music, universal news, commercial propaganda, speeches, Contests,
theater, sports, etc.
