  2. Extreme ultraviolet lithography - Wikipedia

    en.wikipedia.org/wiki/Extreme_ultraviolet...

    Extreme ultraviolet lithography (EUVL, also known simply as EUV) is a technology used in the semiconductor industry for manufacturing integrated circuits (ICs). It is a type of photolithography that uses 13.5 nm extreme ultraviolet (EUV) light from a laser-pulsed tin (Sn) plasma to create intricate patterns on semiconductor substrates.

    UV observations can also provide essential information about the evolution of galaxies. They can be used to discern the presence of a hot white dwarf or main sequence companion in orbit around a cooler star. [3] [4] The ultraviolet universe looks quite different from the familiar stars and galaxies seen in visible light.

    34 North 118 West by Jeff Knowlton, Naomi Spellman, and Jeremy Hight is one of the first locative hypertexts. Published in 2003, the work connected Global Positioning System (GPS) data with a fictional narrative on an early tablet PC connected to Global Positioning devices [ 1 ] to deliver a real-time story to a user.

  7. Ultraviolet index - Wikipedia

    en.wikipedia.org/wiki/Ultraviolet_index

    The UV index is a number linearly related to the intensity of sunburn-producing UV radiation at a given point on the Earth's surface. It cannot be simply related to the irradiance (measured in W / m 2 ) because the UV of greatest concern occupies a spectrum of wavelengths from 295 to 325 nm, and shorter wavelengths have already been absorbed a ...

Teledyne Ryan also developed a third-generation Model 166 Firebee II with supersonic performance, with the U.S. Navy awarding a development contract to the company in 1965. Initial flight was in 1968.

  9. Ultraviolet - Wikipedia

    en.wikipedia.org/wiki/Ultraviolet

    Ultraviolet radiation, also known as simply UV, is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun.
