Science / Weather / Ultraviolet: Electromagnetic radiation that has a wavelength shorter than visible light and longer than x-rays. Although it accounts for only 4 to 5 percent of the total energy of insolation, it is responsible for many complex photochemical reactions, such as fluorescence and the formation of ozone.
Science / Chemistry / Ultraviolet Light: Electromagnetic radiation with wavelength longer than that of x-rays but shorter than that of visible light. Ultraviolet light can break some chemical bonds and cause cell damage. MORE
Entertainment / Photography / Near Ultraviolet: Are wavelengths from about 400nm down to 250nm. Most photographic emulsions are sensitive to this range of bands. MORE
Entertainment / Photography / Ultraviolet (UV): Part of the electromagnetic spectrum from about 400nm down to 1nm. It is invisible to the human eye, but most photographic materials are sensitive to near uv bands down to 250nm. It records as increas MORE
Health / Vitamins / Zinc Oxide: Mineral essential to human nutrition, helps the body produce energy, maintains the cell membrane stable through cellular stabilization processes, antioxidant and immunity enhancer, responsible for nor MORE
Entertainment / Photography / X Ray: Are electromagnetic radiations beyond ultraviolet which, when passed through a solid object and allowed to act upon a sensitive emulsion, form a shadow image of the internal structure of the object. MORE
