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 skin more deeply than UVB and is largely responsible for skin aging. UVB radiation falls within the range of 280 nm to 315 nm. This type of UV radiation is a primary cause of sunburn and plays a significant role in the development of skin cancer. UVC radiation has the shortest wavelengths, from 100 nm to 280 nm. This is the most energetic form of UV radiation and is largely absorbed by the Earth's atmosphere, so very little reaches the surface. UVC is used in sterilization applications due to its germicidal properties. The interaction of UVvåglängd with matter is dependent on the specific wavelength, affecting its absorption, reflection, and transmission characteristics.
