The phrase "at ultraviolet" is not correct and does not convey a clear meaning in written English.
It may be intended to refer to something occurring or being measured at ultraviolet wavelengths, but the phrasing is awkward and unclear.
Example: "The experiment was conducted at ultraviolet wavelengths to observe the effects on the samples."
Alternatives: "in the ultraviolet range" or "at UV wavelengths".
Soho has an instrument on board that maps the solar wind by measuring emissions from hydrogen atoms at ultraviolet wavelengths.
Now there are immersive dining experiences at Ultraviolet, in China, and El Celler de Can Roca, in Spain, and a sonic wine bar in New Zealand.
When astronomers observe the Sun from space at ultraviolet wavelengths, the chromosphere is found to emit lines formed at high temperatures, spanning the range from 10,000 to 1,000,000 K.
An image of the corona obtained at ultraviolet wavelengths has a much more diffuse appearance as compared with lower temperature regions, suggesting that the hot material in the magnetic elements spreads outward with height to occupy the entire coronal space.
When observed at ultraviolet wavelengths, the clouds exhibit distinctive dark markings, with complex swirling patterns near the equator and global-scale bright and dark bands that are V-shaped and open toward the west.
Such theatrics are all part of the show at Ultraviolet, an experimental new restaurant opened in Shanghai by the French chef Paul Pairet, whose aim is to deliver a multisensory eating experience that goes beyond the mere taste of the food.
Towards these goals, we have performed theoretical and experimental evaluations of an approach for broadband measurement of absorption and reduced scattering coefficients at ultraviolet-visible wavelengths.
The classic Y-shaped feature has often been discerned at 2.02 µm in the global views, suggesting some correspondence between the mechanisms or processes creating or contributing to the contrasts seen at the ultraviolet and at 2.02 µm (image b).
The space weather of Earth's upper neutral and ionized atmosphere is strongly influenced by energy injections at high latitudes connected with magnetosphere-ionosphere coupling and solar radiation variability at extreme ultraviolet wavelengths.
The other operated at extreme ultraviolet wavelengths.
At long ultraviolet wavelengths, methane, ammonia, water, and hydrogen are all transparent, and much of the solar ultraviolet energy lies in this region of the spectrum.
