3. ultraviolet
   Light that is so blue humans cannot see it. A band of the electromagnetic spectrum between the visible and the X-ray. Photons of ultraviolet light are more energetic than photons of visible light.

8. Ultraviolet
   Ultraviolet (UV) radiation is invisible. It is a form of electromagnetic radiation, with a wavelength just shorter than that of visible violet light. UV radiation can be used to treat skin conditions like acne. Humans use UV light from the Sun to produce vitamin D3 (used in the kidneys and liver). ...

10. Ultraviolet
    (UVA,UVB) Ultraviolet light is light that we cannot see. But it is an important part of sunlight. Ultraviolet light is divided into UVA, UVB and UVC. UVC cannot get through the ozone layer to reach us. But UVA and UVB can both increase the risk of skin cancer, including malignant melanoma. Sunbathin...

15. ultraviolet
    Continuous spectrum beyond the violet end of the visible spectrum (wavelength less than 400nm), and above the X-ray wavelengths (greater than 5nm). Glass absorbs UV, so optical systems at these wavelengths have to be made of quartz. Nucleic acids absorb UV most strongly at around 260nm, and this is the wavelength most likely to cause mutational damage (by the formation of thymine dimers). It is the UV component of sunlight that causes actinic keratoses to form in skin, but that is also required for Vitamin D synthesis.
