extreme ultraviolet

(EUV, XUV)
(electromagnetic radiation in the range of 10nm-124nm)

Extreme ultraviolet (EUV or XUV) is the shortest wavelength ultraviolet radiation, adjacent to X-ray and at the far end of the UV spectrum from visible light. A typical cited wavelength-range is 10-124nm (ultraviolet's is 10 nm to 400 nm).

EUV is completely absorbed by the atmosphere and its astronomical observation is carried out by space observatories. It is considered ionizing radiation (capable of significant ionization). Observation is used to study the corona of the Sun (revealing the Sun's magnetic topology) and to study the interstellar medium.
