What is xuv?

XUV stands for "eXtremely Ultraviolet," referring to a range of electromagnetic radiation wavelengths between about 10 to 124 nanometers. This part of the spectrum is significant in various scientific fields, including astrophysics, materials science, and semiconductor manufacturing, due to its ability to penetrate materials and its applications in imaging and spectroscopy. XUV light is used in advanced technologies such as photolithography for microchip production and in studying the properties of atomic and molecular structures.
