Ultraviolet radiation,that portion of the electromagnetic spectrum extending from the violet, or short-wavelength, end of the visible light range to the X-ray region. Its wavelengths are between 400 and 10 nanometers. Learn more about ultraviolet radiati
Ultraviolet light is a type of electromagnetic radiation that makes black-light posters glow, and is responsible for summer tans — and sunburns. However, too much exposure to UV radiation is damaging to living tissue. Electromagnetic radiation comes from the sun and transmitted in waves or partic...
In subject area: Physics and Astronomy 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...
whereε0is the vacuum dielectric constant,cis the light velocity in vacuum,n1andn2are the refractive indices at the fundamental and SHG frequencies ω and 2ω, respectively, andI1is the intensity of fundamental light. Clearly, the SHG conversion efficiencyI2/I1is mainly determined by the transpa...

Treating rosacea begins with avoiding its triggers. Though they vary among patients, UVR is regarded as a universal rosacea trigger. Until now, the mechanism underlying this pathology has resisted characterization. The work of Kulkarni and colleagues sheds light on how UVR causes rosacea inflammation...
Ultraviolet light provides a major input to non-image-forming light detection in mice 2012, Current Biology Citation Excerpt : These results show that the circadian system is capable of integrating UV light in a manner comparable to light in the visible spectrum [6, 9]. Collectively, the data...
