Question: What Is the Wavelength of Ultraviolet Light?
Answer: Ultraviolet light is light or electromagnetic radiation that occurs between the visible spectrum and x-rays. Ultraviolet light is light in the range of 10 nm to 400 nm with energies from 3eV to 124 eV. Ultraviolet light gets its name because it is the light closest to the violet portion of visible light.
