Technology is a deep ocean and the more we get deeper into it the more treasurous it gets. With better technology in the world of software, the need for better connectivity and internet has rose over the years and so has the demand for a more and better spectrum. The invention or rather discovery of Li-Fi, has somehow quenched the thirst for more spectrum. Light Fidelity or better known as Li-Fi has sworn in as a savior and has provided the world an alternative to the more conventional and monotonous applications like Wi-Fi, Bluetooth etc. Discovered by Prof. Harald Haas, at the University of Edinburgh in UK, Li-Fi provides a mindboggling internet connectivity with a download speed up to 10GB/s and that too with the use of the basic LED lights. It works in the visible light spectrum from BLUE to RED and overcomes the drawbacks faced by the likes of UV Rays, X-Rays, and GAMMA Rays. It works by the principle of data through illumination. Its applications in the field of Medicine and in Sea and oceans make it a wonderful thing in itself. It is considered to be a big thing and have a big global market in the upcoming decade and leave humanity and technology spellbound.
