Ultraviolet radiation refers to a form of electromagnetic radiation with wavelengths shorter than visible light, divided into UVC, UVB, and UVA fractions. It carries higher energy photons than visible light and can have harmful effects on DNA, leading to skin aging, cancer, and other health issues...
Relating to electromagnetic radiation having wavelengths shorter than those of visible light but longer than those of x-rays. See more at electromagnetic spectrum. Noun Ultraviolet light or the ultraviolet part of the spectrum. See Note at infrared. The American Heritage® Student Science Dictionary...
Ultraviolet radiation from high-intensity sources has well-known acute effects on the eye and skin, consisting primarily of photokeratoconjunctivitis and sunburn, which are enhanced in the presence of photosensitizing agents. Long-term elevated exposure to low-level ultraviolet radiation is also ...
solar ultraviolet radiation太阳紫外辐射;阳光紫外缐照射 ultraviolet同义词 adj. [光]紫外的;紫外线的 extraviolet ultraviolet词源中文解释 "可见光谱紫色端之外," 1840年,来自 ultra- "之外" + violet "紫色"。 Ultra-red(1870年)曾是现在所称的 infra-red 的旧称。
Definition The lunar surface has a complex plasma environment due to incoming solar wind flux and charged micron-sized dust particles and the presence of solar ultraviolet (UV) radiation. UV resonance fluorescence of solar radiation provides a sensitive detection of major elemental constituents, such ...
A method of computing the diffuse reflection and transmission radiation by an inhomogeneous, plane-parallel planetary atmosphere with internal emission source is discussed by use of the adding method. If the atmosphere is simulated by a number of homogeneous sub-layers, the radiation diffusely reflecte...
As the earth's atmosphere absorbs most of the space (solar) UV radiation, any UV application is based on man-made UV sources. In the solar spectrum, the high-energy UV photons (10–120 nm; 124–10 eV) are capable of ionizing molecules by a single-step energy transfer process to ...
Although the transmittance benefits of AR coatings were confirmed, most coatings were found to reflect UV radiation at unacceptably high levels. Tinted sun lenses also were tested with similar results. Frame and lens parameters were evaluated, confirming that eyewear that incorporates a high wrap ...
Therefore, due to the presence of the zero-point length in the quantum spacetime, a bosonic ideal gas which behaved like radiation at very small energy scales undergoes a continuous phase transition and near the Planck scale behaves as if it is a fluid with equation of state parameter 2. ...
