Spectral line at 121.6 nm, 10.20 eV. Extreme ultraviolet: EUV 10–121 10.25–124, 1.642–19.867 Entirely ionizing radiation by some definitions; completely absorbed by the atmosphere. Vacuum ultraviolet VUV 10–200 6.20–124, 0.993–19.867 Strongly absorbed by atmospheric oxygen, though 150–200 nm wavelengths can propagate through nitrogen.
The field of view ( FOV) is the angular extent of the observable world that is seen at any given moment. In the case of optical instruments or sensors, it is a solid angle through which a detector is sensitive to electromagnetic radiation. It is further relevant in photography .
Corrective lens. A corrective lens is a transmissive optical device that is worn on the eye to improve visual perception. The most common use is to treat refractive errors: myopia, hypermetropia, astigmatism, and presbyopia. Glasses or "spectacles" are worn on the face a short distance in front of the eye.
Certainly, shareholders were much more comfortable signing off on certain governance changes. There were 252 such proposals and 38 were successful out of the 154 that went to a vote between Jan. 1 ...

It can be used to detect objects that range from the mass of a planet to the mass of a star, regardless of the light they emit. Typically, astronomers can only detect bright objects that emit much light ( stars) or large objects that block ...
Google Lens is an image recognition technology developed by Google, designed to bring up relevant information related to objects it identifies using visual analysis based on a neural network. [2] First announced during Google I/O 2017, [ 3 ] it was first provided as a standalone app, later being integrated into Google Camera but was reportedly ...
