Shortwave light is the ultraviolet energy farthest from visible light, shorter than rays in sunlight, and primarily noted for its ability to fluoresce minerals for chemical analysis.
UltraCaution: Do not expose eyes or skin to shortwave ultraviolet light as rays may burn unprotected eyes or skin. UV Blocking Eyewear is recommended.violet light is electromagnetic radiation in the part of the spectrum between x-rays and visible light, approximately 180nm to 400 nm. It differs from light only that its wavelengths are too short to be seen by the human eye.
When UV radiation falls upon phosphors, it causes the phosphors to emit specific radiation. This phenomenon is known as fluorescence. In some materials, the fluorescence linger on and slowly disappears after the UV source is removed. This phenomenon is known as phosphorescence.
