3. Molar absorption coefficient - Wikipedia
Link: https://en.wikipedia.org/wiki/Molar_absorption_coefficient
Description: WEBIn chemistry, the molar absorption coefficient or molar attenuation coefficient (ε) is a measurement of how strongly a chemical species absorbs, and thereby attenuates, light at a given wavelength. It is an intrinsic property of the species.

Description: WEBThe absorption coefficient determines how far into a material light of a particular wavelength can penetrate before it is absorbed. In a material with a low absorption coefficient, light is only poorly absorbed, and if the material is thin enough, it will appear transparent to that wavelength.

6. Absorption (electromagnetic radiation) - Wikipedia
Link: https://en.wikipedia.org/wiki/Absorption_%28electromagnetic_radiation%29
Description: WEBIn physics, absorption of electromagnetic radiation is how matter (typically electrons bound in atoms) takes up a photon 's energy — and so transforms electromagnetic energy into internal energy of the absorber (for example, thermal energy ). [1]

Description: WEBMar 21, 2024 · The absorption coefficient, often represented by the Greek letter alpha (α), is a measure of how quickly the intensity of electromagnetic radiation decreases as it passes through a specific medium. It is typically expressed in units of inverse length, such as inverse meters (m -1 ). The Absorption Coefficient Formula.

Link: https://www.britannica.com/science/absorption-physics
Description: WEBabsorption, in wave motion, the transfer of the energy of a wave to matter as the wave passes through it. The energy of an acoustic, electromagnetic, or other wave is proportional to the square of its amplitude—i.e., the maximum displacement or movement of a point on the wave—and, as the wave passes through a substance, its amplitude ...

Description: WEBThe rate of absorption of light is proportional to the intensity (the flux of photons) for a given wavelength; in other words, as light passes through the material the flux of photons is diminished by the fact that some are absorbed on the way through.
