UVvåglängd
UVvåglängd refers to the wavelength of ultraviolet radiation. Ultraviolet (UV) radiation is a type of electromagnetic radiation that falls within the electromagnetic spectrum between visible light and X-rays. Its wavelengths are shorter than visible light and longer than X-rays. The wavelength is typically measured in nanometers (nm). The UV spectrum is broadly divided into three regions: UVA, UVB, and UVC, based on their wavelengths.
UVA radiation has the longest wavelengths, ranging from approximately 315 nm to 400 nm. It penetrates the
