Wavelength of short ultraviolet radiation is which range?

Explanation:
Focus on where ultraviolet light sits in the spectrum. Short ultraviolet radiation refers to the UV-C band, which spans roughly 180–290 nanometers. Photon energy in this range is high enough to disrupt microorganisms, which is why this band is used for germicidal purposes and certain therapeutic applications. The other ranges listed fall outside UV: 700–1500 nm lies in the near to mid-infrared, 1600–12,000 nm is infrared, and 0.1–3 mm is microwave. So the 180–290 nm range is the ultraviolet one, making it the correct choice.
