Light origins

Where does all this light come from? Most light comes from our sun. Light can be reflected or direct from a source, our main source of direct light is the sun, but what about light from LED’s etc.  So all other light not generated must be reflected unless you are looking at the sun. This means except for direct sunlight all we see has been reflected.

 

Again man has adapted this reflection and fibre optic cables do just that. These cables can control the movement of light. When they are mixed with electromagnetic waves they can carry data. The type and amount of this data can be varied. Data is a stream of information organised in simple yes no or on off (binary)form. The type of data can be anything that can be converted into this binary format.

 

Where does this data come from? Most of it is from computers and cameras. Binary data as this on off information is called is the simplest form of this data. This data can even be transmitted in the very air we breathe. This form of wireless data is the bedrock of our mobile phone world. The transporting of this data has become faster and increases in volume as time has gone by.

 

The main type of data in our mobile phone system is video. This is our sights and sounds converted into streams of data. We are all aware of the moving picture frequency. Pictures shown at speeds over 25 frames a second, appear as continuous motion in our brains. The definition of our video can vary considerably. If you watch a low definition video this is probably the definition in your dreams. Add to that the conversion of our voices and you get video.
