An optical instrument is said to be diffraction-limited if it has reached this limit of resolution performance. Other factors may affect an optical system's performance, such as lens imperfections or aberrations, but these are caused by errors in the manufacture or calculation of a lens, whereas the diffraction limit is the maximum resolution ...
The photosynthetic efficiency is the fraction of light energy converted into chemical energy during photosynthesis in green plants and algae. Photosynthesis can be described by the simplified chemical reaction. 6 H 2 O + 6 CO 2 + energy → C 6 H 12 O 6 + 6 O 2. where C 6 H 12 O 6 is glucose (which is subsequently transformed into other sugars ...
QI. QI ( Quite Interesting) is a British comedy panel game quiz show for television created and co-produced by John Lloyd. The series currently airs on BBC Two and is presented by Sandi Toksvig. It features permanent panellist Alan Davies and three guest panellists per episode; the panellists are mostly comedians.
This image shows an early, experimental tool. Extreme ultraviolet radiation ( EUV or XUV) or high- energy ultraviolet radiation is electromagnetic radiation in the part of the electromagnetic spectrum spanning wavelengths shorter than the hydrogen Lyman-alpha line from 121 nm down to the X-ray band of 10 nm. By the Planck–Einstein equation ...
In this zone, dissolved oxygen is reduced, light is limited to long wavelengths (e.g., red and infrared) left-over by oxygenic phototrophs (e.g., cyanobacteria), and anaerobic metabolisms (i.e., those occurring in the absence of oxygen) begin introducing sulfide and bioavailable nutrients (e.g., organic carbon, phosphate, and ammonia) through ...
wirelesspowerconsortium .com. Qi (pronounced / tʃiː / CHEE; [1] from simplified Chinese: 气; traditional Chinese: 氣; pinyin: qì) is an interface standard for wireless power transfer using inductive charging. The standard allows compatible devices, such as smartphones, to charge their batteries when placed on a Qi charging pad, which can ...
Synchrotron light source. A synchrotron light source is a source of electromagnetic radiation (EM) usually produced by a storage ring, [ 1] for scientific and technical purposes. First observed in synchrotrons, synchrotron light is now produced by storage rings and other specialized particle accelerators, typically accelerating electrons.
X-ray optics. X-ray optics is the branch of optics that manipulates X-rays instead of visible light. It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and ...
