Sentences with phrase «visible wavelengths»
"Visible wavelengths" refers to the range of colors in light that our eyes can see. This means the colors that are within our visual spectrum, like red, orange, yellow, green, blue, and violet. Full definition

«These results are broadly applicable to any phase recovery and holographic imaging problem, and this deep - learning - based framework opens up myriad opportunities to design fundamentally new coherent imaging systems, spanning different parts of the electromagnetic spectrum, including visible wavelengths and even X-rays,» said Ozcan, who also is an HHMI Professor at the Howard Hughes Medical Institute.
Combining more telescopes and moving to visible wavelengths broadens the science cases even more.
«We found in the Pan-STARRS1 imaging that SDSS1133 has been getting significantly brighter at visible wavelengths over the last 6 months and that bolstered the black hole interpretation and our case to study SDSS1133 now with HST,» said Yanxia Li a UH Manoa graduate student involved in the analysis of the Pan-STARRS1 imaging in the study.
Such compounds double bonds that readily absorb UV light, then re-radiate the energy at relatively harmless visible wavelengths.
Cloud droplets scatter visible wavelengths impartially (hence, clouds usually appear white) but very efficiently, so the reflectivity of clouds to solar radiation is typically about 50 percent and may be as high as 80 percent for thick clouds.
Studies of other stars, as well as theoretical modeling, have shown that Sun - like stars begin their life about 20 to 30 percent fainter in visible wavelengths than the Sun is at present.
In a study published in Solar and Stellar Astrophysics, the researchers say they saw the red supergiant star N6946 - BH1 flare a million times brighter than our sun for several months in 2009 before fading out of visible wavelengths, a likely sign of a brand - new black hole.
