What Is The Frequency Of Ultraviolet And How It Affects Your DNA

Nanowerk: Optical frequency combs make ultraviolet spectroscopy more sensitive and more precise A metasurface made of arsenic trisulphide nanowires (yellow) transmits an incoming near-infrared frequency (red) as well as its third harmonic ultraviolet frequency (violet), which would normally be ... Physicists in the US have created an optical frequency comb that operates in the extreme ultraviolet (XUV). Touted as the first practical comb to work in this region of the spectrum, the device could ... (Nanowerk News) In a recent publication in Nature ("Near-ultraviolet photon-counting dual-comb spectroscopy"), researchers at the Max Born Institute (MBI) in Berlin, Germany, and at Max-Planck ... High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see. Extreme ...
