In physics, absorption of electromagnetic radiation is the way in which the energy of a photon is taken up by matter, typically the electrons of an atom.
Absorption spectroscopy refers to spectroscopic techniques that measure the absorption of radiation, as a function of frequency or wavelength, due to its interaction with a sample.
An airborne observatory is an airplane, airship, or balloon with an astronomical telescope.
The Beer–Lambert law, also known as Beer's law, the Lambert–Beer law, or the Beer–Lambert–Bouguer law relates the attenuation of light to the properties of the material through which the light is travelling.
A blue hole is a large marine cavern or sinkhole, which is open to the surface and has developed in a bank or island composed of a carbonate bedrock (limestone or coral reef).
Calar Alto is the highest peak (2168 m over sea level) in the Sierra de Los Filabres, a mountain chain in Andalusia, Spain.
Calcium silicate is the chemical compound Ca2SiO4, also known as calcium orthosilicate and is sometimes formulated as 2CaO·SiO2.
Calorescence is when matter absorbs infrared radiant energy and emits visible radiant energy in its place.
CAMPUS (acronym for Computer Aided Material Preselection by Uniform Standards) is a multilingual database for the properties of plastics.
The color of water varies with the ambient conditions in which that water is present.
Cyan is a greenish-blue color.
Drought tolerance is the degree to which a plant is adapted to arid or drought conditions.
The aging of natural and artificial polymeric materials is a natural phenomenon in metals, glass, minerals and other inorganic materials.
Fused quartz or fused silica is glass consisting of silica in amorphous (non-crystalline) form.
Hydroxyl ion absorption is the absorption in optical fibers of electromagnetic waves, including the near-infrared, due to the presence of trapped hydroxyl ions remaining from water as a contaminant.
The index of physics articles is split into multiple pages due to its size.
The Institut de radioastronomie millimétrique (IRAM) operates two radio astronomy telescopes at millimeter wavelengths, which are open to the international astronomical community: the 30 m single-dish radio telescope located on Pico Veleta (2850 m) in the Spanish Sierra Nevada (Andalucia, Spain), and the six-antenna Plateau de Bure Interferometer (2550 m) in the French Alps.
John Twiss Blake (c. 1901-June 26, 1987) was a research scientist at the Simplex Wire and Cable company.
John Tyndall FRS (2 August 1820 – 4 December 1893) was a prominent 19th-century physicist.
The refractive index of water at 20 °C is 1.3330.
The following outline is provided as an overview of and topical guide to water: Water is a chemical substance with the chemical formula H2O.
The photic zone, euphotic zone (Greek for "well lit": εὖ "well" + φῶς "light"), or sunlight or (sunlit) zone is the uppermost layer of water in a lake or ocean that is exposed to intense sunlight.
Photosynthetically active radiation, often abbreviated PAR, designates the spectral range (wave band) of solar radiation from 400 to 700 nanometers that photosynthetic organisms are able to use in the process of photosynthesis.
Photovoltaic thermal hybrid solar collectors, sometimes known as hybrid PV/T systems or PVT, are systems that convert solar radiation into thermal and electrical energy.
Water is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. It is by far the most studied chemical compound and is described as the "universal solvent" and the "solvent of life". It is the most abundant substance on Earth and the only common substance to exist as a solid, liquid, and gas on Earth's surface. It is also the third most abundant molecule in the universe. Water molecules form hydrogen bonds with each other and are strongly polar. This polarity allows it to separate ions in salts and strongly bond to other polar substances such as alcohols and acids, thus dissolving them. Its hydrogen bonding causes its many unique properties, such as having a solid form less dense than its liquid form, a relatively high boiling point of 100 °C for its molar mass, and a high heat capacity. Water is amphoteric, meaning that it is both an acid and a base—it produces + and - ions by self-ionization.
Proteorhodopsin (also known as pRhodopsin) is a family of over 50 photoactive retinylidene proteins, a larger family of transmembrane proteins that use retinal as a chromophore for light-mediated functionality, in this case, a proton pump.
The South Pole Telescope (SPT) is a 10 meter (394 in) diameter telescope located at the Amundsen–Scott South Pole Station, Antarctica.
Space-based solar power (SBSP) is the concept of collecting solar power in outer space and distributing it to Earth.
A tangzhuang is a kind of pseudo-traditional Chinese jacket with a straight collar.
Tasikmalaya Regency (pronounced) (Kabupaten Tasikmalaya, Sundanese) is a regency (Indonesian: kabupaten) in the province of West Java, Indonesia.
The visible and near-infrared (VNIR) portion of the electromagnetic spectrum has wavelengths between approximately 400 and 1400 nanometers (nm).
Water is a transparent, tasteless, odorless, and nearly colorless chemical substance that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms.
90482 Orcus, provisional designation, is a trans-Neptunian object from the Kuiper belt with a large moon, Vanth.
