How has modulated light impacted on modern media
Am doing my research paper on the type of impact modulated light has had on contemporary media. in my paper I’ve asked myself questions. what modulated light is? who discovered it?
the pros and cons of having modulated light in telecommunications. At first, I chose to do it on Alexander Graham bell. but his work was so vast that I narrowed it down to a one of his discovery’s.
in doing so I discovered that were able to use light as a form of telecommunications in order to deliver content to its viewer at super-fast speeds. This is what helps me to think about we’re LIFI (modulated light) is going as a gamer. people and I are always talking about what would gaming be like if the loading time were a matter of seconds?.an the data was sent thru LIFI” modulated light”.
it would not take more than a second to receive the data just all your information at the flick of a switch.
to find the origins of modulated light.
I researched more on Mr e.g. bell and his background how he became so interested in what we call today ,modulated light an had to look an what if found was (1) in February of 1880 AG bell (Alexandra graham bell)discovered that you use a diaphragm attached to a metal grating and a selenium receiver you able to send a message thru a beam of light (hence the sun).on a device called the photo phone as shown bellow(fig1) .now that he released that he could send a voice message through a beam of light was the pinnacle turning point in his life.
that how modulated light was born.
(2) Mr AGB also invented the telephone.
he became interested in the science of sound because both his wife and mother were deaf.
over the years people have tried to recreate the same experiments.
A found an article what I looked at.
It was about a team trying to make a type of light to send communication to satalights an space-aircraft but they kept running into natural cause that halted the photo-phone tests. stuff like weather e.g., fog, rain stuff along them lines. (3) Li-Fi!! Al, tell you abet about life .... life is a type of light fidelity which turns LED lamps into internet and broadcast data transmitters, creating a new form of high-speed, optical wireless communication that leverages the visible and infrared (IR) light spectrums.
if you watch this video on modulated light you would beta understand how you can create ur own. https://www.exploratorium.edu/video/modulated-led-introduction

So were is modulated used in modern world?there was a reference to this that basically said Life is currently being used in more than 130 real world scenarios in over 23 countries, including one in a high school in Ayr you can find LIFI (modulated light) in few place test are bin done all the time to see if modulated light is legible in the real world scenario you can send data without any disturbances like weather an stuff.
(2) in Modern communications systems like long distance phonelines and high-bandwidth communication lines for computers use modulated light signals. The relatively high frequencies of visual light can carry a lot more information than lower-frequency radio waves.you can find them in
Architectural light bulbs that can carry like a ( LIFi)light fidelity signal data more further distance an faster uplink an downlinks then your conventional WiFi (wire fidelity) you can find them doing test to see if they can transfer data from earth to space stations in just a few seconds with a laser beam.
You can find them using it in old cable lines. they still use modulated light in experiments. maybe in the future the advancement in lifi tech will advance so much that you will see them use lifi tech for making machine’s that project a human like hologram the has that’s has human character features. You find little hints in films like….. blade runner 2049 it’s a 2019 film were the LIFI is used for a hologram machine that’s called
(4) Joi can be projected into three-dimensional space (as a hologram) and interact with a real person in the room. And with the help of a small device called an “emanator,” she can literally materialise as a corporeal form, able to touch and feel things in the real world. When we look to the future when it comes to LIFI the emerging tech you realise what type of tach devices will eventually come in to production the lifi (modulated light)tech we haVE now is very minimal an expensive like the lifi tach light bulb it come in at around £1000 a unit but worth it when you think of what is possible with this emerging tech
you find them using LIFI to transmit data like blog , streaming videos ,social media ,games etc .there some test are bin done with modulated light in stem cell research there trying to create a beam of light that detects viruses an it vibrate light on the stem cell abasically breaks the virus in to peace’s so it can not regrow.
When you look at wether it as a future withinTelecommunication you say yes because cause with modulated light you can do anything from sending data to curing diseases as it said in a blog that a Carnot find now that (5)these things are going to change the face of communications world within a short time, as billions of data can be transferred in a fraction of seconds. A cure disease with laser beams. Aircraft and hospitals where the usage of Wi-Fi is a problem can use this technology for communication. The Li-Fi communications are possible in industrial areas where the RF

communications can cause antenna sparks and the usage of electromagnetic waves will be of great interference and security issue.(1) they say that lifi tec is the new emerging form of data transfer were the binary data is transferred in the form of flickering lights its optical wireless communication(own) LIFI can transmit data at lightning fast speeds up-to 100 times faster then traditional WiFi .data is sent with flickering led bulbs billions times a second too fast for the normal eye to see. when you look at where we were 20 years ago to where we are now with contemporary media we have come a long way in the ways of improving on the old things.
like windows os for instance they come a long way in the way of improving on the old things windows 95 -10 there has bin a lot of improvements.LIFI will make games loading time an rendering a lot faster so it will cut waiting time in half be able to produce games that are a lot faster transfer of game data with in second there was this article with many references one says(6) liFi offers several advantages, as Professor Harald Haas from the University of Edinburgh explains: “It’s secure, simply because light doesn’t go through walls. Somebody on the street would find it hard to build an optical system to intercept that light … whereas with Wi-Fi, data interception can be achieved from a safe distance. Basically meaning it’s got good security for hi tech giants this would mean everything would be confined to the build unless transferred across the visual spectrum .like in the picture on the right..
there would be no need for wires it would be all wireless could you Imagine ever device like TVs, monitors, console ,PCs all bin wireless with out wire an it was all done by light rather then electricity do you think it would be a good thing to have a hologram machine in the future cause think about it like this if light meaning the sun is are life an we can not live with out it an the way we feel the sun light do you think if holograms were made from modulated light that maybe they would be so intelligent that they may out live are race an become the intellects of the planet?
How can energy travel across empty space? Find out, then test what you've learned: build a simple device that transmits the signal from a radio to a light bulb...and then to another radio.
