Shorter wavelengths of invisible ultra-violet light, measured in Nanometers (nm), transport more energy than longer wave-lengths of visible light. That energy is finding its way into an increasing variety of high-tech applications, such as disinfecting water of hazardous micro-organisms or in the development of paint that dries in seconds. The highly competitive field of computer chip lithography has chemists and physicists working with EUV Extreme ultra-violet light technology. Chemical engineers have designed light sensitive paints that dry quickly under a high energy ultraviolet radiator. New light technologies are being used to manufacture semiconductors, lenses and many other small scale advances in nanotechnology.
