RADIO

The object that I will expose in this essay is the radio, since for me it is one of the most important inventions, when talking about communication and connection to long distances thanks to the electromagnetic waves of the radio, because it is one of the technological devices that I use the most in my daily life, to listen to music at different recreational moments or to concentrate.

The radio was invented in 1894, by the Italian inventor Guglielmo Marconi who built the first complete wireless telegraphy system, using the wave theory that existed prior to the configuration of the device. It is evident that since the year in which this technological apparatus was created, it has presented a great evolution, which is constant. First the radio was used to communicate, but now it is given a character of entertainment, to listen to music on different stations, on CD, auxiliary, etc.

Before the radio was a device of great magnitude, that is, it was very large and not very light, however if we compare it with the now, we realize that each time the device is decreasing the volume and each time is more efficient and Best Quality. Even radio waves can be picked up by the cell phone and the computer and so we can make use of it in other technological devices.

This object clearly changed the lives of people, in all aspects, since being one of the first technological devices that enabled communication between people over long distances, it generated a faster, more fluid communication and was one of the devices that started of globalization in the word. Nowadays the music that can be played by this device is indispensable, since for me music determines the moment a lot, like for example, a party without a radio or without an apparatus that reproduces the waves, it is not the same.
