紫外光的分类 Ultraviolet light is light with a wavelength shorter than ≈ 400 nm, the lower limit of the visible wavelength range. Different definitions are used for distinguishing different spectral regions: The near-UV spectral region ranges from 400 nm down to 300 nm. The middle-UV region ranges from 300 to 200 nm, and shorter wavelengths from 200 nm down to 10 nm belong…
