The color of the objects we see in the natural world is a result of the way objects interact with light. When a light wave strikes an object, it can be absorbed, reflected, or refracted by the object. All objects have a degree of reflection and absorption. Note: In the natural world, light can also be transmitted by an object. That is, light can pass through an object with no effect (an x-ray

Kortfattad beskrivning av reflektion, absorption och transmittans av ljus. Lämpligt för grundskolans senare år.

When electromagnetic radiation is absorbed, an electron of an atom goes from a lower energy state to a higher energy state through the “electron jump”. Chlorophyll a absorbs light mainly in the red and blue regions. Accessory pigments such as chlorophyll b, xanthophyll and carotene absorb light from other regions of the spectrum and pass the energy onto chlorophyll a. The accessory pigments broaden the absorption spectrum so that more energy is available for photosynthesis. The absorptance, which is the fraction of the incident laser light which is absorbed, depends on a number of different parameters. These include laser parameters such as intensity, wavelength, polarisation and angle of incidence and material properties such as composition, temperature, surface roughness, oxide layers and contamination. Absorption and transmission spectra represent equivalent information and one can be calculated from the other through a mathematical transformation.

Chem. Phys. , 18 ( 2018 ) , pp. 9061 - 9074 , 10.5194/acp-18-9061-2018 Most optical instruments that quantify light absorption, however, are unable to distinguish one type of absorbing aerosol from another. It is thus instructive to separate total absorption from these different light absorbers to gain a better understanding of the optical characteristics of each aerosol type. For beach-goers, experts always recommend a healthy coating of sunscreen to protect the skin from those pesky ultraviolet (UV) rays. But sunlight contains more than just UV light.

Our findings improve our understanding of fundamental properties of fluorescent proteins, and expand the possibilities of development and applications of genetically encoded fluorescent probes. Absorption of light by photoreceptors o The photochemical reactions occurred in the photoreceptors by the absorption of light forms the basis of the visual system 37. Light Filters o Material used to absorb or transmit light of all wavelength equally i.e. neutral density filter or selectively such as the colored filters E.g. green filters, blue filters Light Absorption in Solar Cells The Setfos absorption module uses the transfer matrix formalism for the fast calculation of the photon flux across a solar cell. Arbitrary sequences of coherent and incoherent layers can be considered in the device stack and their total effect on the solar cell absorption can be computed.
