Recent studies have shown that a wide variety of such contaminants exist at trace concentrations in all water supplies and in the air. Ultraviolet germicidal irradiation (UVGI) is a method of disinfection that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their [...]
The study of the interaction between matter and electromagnetic radiation is known as spectroscopy. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, by a prism. Spectroscopic data is often represented by an emission spectrum, a plot of the response of interest as a function of wavelength or frequency. [...]
Li-Fi is a technology for wireless communication between devices using light to transmit data and position. In technical terms, Li-Fi technology – visible light communication system – is capable of transmitting data at high speeds over the visible light spectrum, ultraviolet and infrared radiation. The term Li-Fi was coined by University of Edinburgh Professor Harald Haas during a TED Talk in 2011. [...]
