| The Television |
| The t.v is a technological device that has been very useful. Long time ago people didnt have the opportunity to get access to a machine that showed them some images in a screen until one day, a very intelligent man called John Logiebaird invent this machine in 1926. Pablo Nipkov was other of the first one to get an image and in 1940 the color T.v was getting better thanks to the scientist Peter Goldmark who improved the transatlactic transmission, but the one who really invent the T.v. was John Logiebaird. He decided to invent this technology because he thougth that the people needed to acess all that happened around the world and some T.v shows for entertainment. A t.v. works by a wound that is electromagnetic it consists of a series of fluctuations that corresponds to the fluctuation of the ligth intensity for a image to be explored, this electromagnectic flutuations are the ones that send a image to the screen, but there is also another thing that is a frequency and it transport the sound, also it has a flat disk with little holes that when it get turn around you can see whole image that is inside the screen. The waves travel until they get connected with electro magnetic flutuations, then they go to the main point that is the one encharged of sending information outside. The T.v also has some holes at the top that is where the sound comes from. This is how we have the opportunity to watch t.v. Today there is Television in many homes of the world. This wonderful technology also affect society. LEst see why it is so. Some people get to like very much that they get addicted to it nd then the people could not live without T.v, sometimes they have to got to any place and they do not go because they prefer to stay watching there best T.v show or something like that. Ohter way it because they were always at thme and they never go outside to do exercise, also when the t.v is broken they trougth it to the garbage and that is just pollution, this are some of the ways that the T.v affect the society I think that in the future the t.v is going to be much bigger kind of watching a movie in theather you can see better the effects of the movie and you can also have a better sound, it would be much quickly and made of different materials (stronger9 and also you can have a small T.v in your hand to take it everywhere. It was interesting to learn about the t.v because I can learn many things about it and specially because it is a machine everybody knew it but they dont know how it works. I hope you enjoy reading about the T.v and that you learn something about it. |
