Television (টেলিভিশন) Or, Use and Abuses of Television (টেলিভিশন এর সুফল ও কুফল)

Introduction: The word 'tele' means 'distance' and 'vision' means 'sight'. So television is a thing that carries our photographic pictures along with our voices to the farthest corner of the world. It is the most up-to-date means of communication.

Its invention: The idea of television came first in the mind of Paul Nijskow, a German scientist. He explained the idea of scanning a picture by breaking it up into small elements of light and shade. 

A number of scientists worked hard for quite a long period. At last, an English scientist named Beyard was able to invent television in 1945. 

How the system works: Two principles work behind the television transmission of sound and transmission of pictures or images. It was found that like sound, light also could be transformed into electric current. 

A picture is scanned to break it up into small elements of light and shade which are transformed into electric current by the Cathode Ray Tube. 

These light waves are received by the receiving sets of television where through the mechanical process they are rechanged and transformed into the image of the original pictures.

Uses of television: Television is the most modern means of communicating ideas and thoughts. It serves much more morally than a radio. It is like a stage, where performers are seen and heard. It gives us news on national and international matters. It is a source of recreation. 

After days of hard work, we sit before a television set and hear music and song. We enjoy drama, dance and other recreational programmes. It not only entertains but also instructs us. Television represents the country's taste and refinement. 

People can have knowledge of the whole world from the television screen. Even the illiterate may get educative lessons from a television set. Sports programmes such as football matches, and cricket matches are relayed on television and interested persons get much interest. 

The politicians get important political news and the general people can enjoy themselves through various programmes.

Demerits: Television has some demerits also. Sometimes students prefer enjoying television to studying. Young boys often sit before the television instead of playing on the field. 

Thus it hinders the growth of the young generation. Sometimes naked scenes and obscene films are shown on television which causes great harm to our young generation.

Conclusion: Despite having some demerits modern civilization without television cannot be thought of. It entertains as well as instructs us. So television is a boon of science for mankind.
