Subsequently, the light wave with that given frequency is absorbed by the object, never again to be released in the form of light. So the selective absorption of light by a particular material occurs because the selected frequency of the light wave matches the frequency at which electrons in the atoms of that material vibrate.

Absorption spectroscopy is one way to study the energy levels of atoms and molecules. An absorption spectrum measures the amount of light absorption as the light's wavelength is varied.. The spectrum of an atom or molecule depends on its energy-level structure.This makes absorption spectra useful for identifying elements and compounds, because each spectrum acts like a fingerprint.

Absorption of Light [/caption] Those who can remember sitting through elementary science class might recall learning that with all matter, light is absorbed and converted into energy.

The absorption of light occurs when a ray of light strikes a surface. The energy from the light is transferred to the surface material. The transfer creates heat (usually small amounts). An absorbing surface prevents reflection or diffusion of light striking on the surface. In practice, perfect absorption does not exist.

en.wikipedia.org/wiki/Absorption_(electromagnetic_radiation)

In 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). A notable effect (attenuation) is to gradually reduce the intensity of light waves as they propagate through a medium.

Absorption of Light the decrease in intensity of optical radiation (light) as it passes through a material medium owing to its interaction with the medium. In the process of absorption, the energy of the light is converted to different forms of internal energy of the medium; it may be completely or partially reemitted by the medium at frequencies other ...

Interaction of Light with Matter: Absorption and Emission of Light It should come as no surprise to you that atoms and molecules (which are simply bound collections of two or more atoms) can absorb light (= energy!). If they didn't, you could simply flick a light on and off, and then sit back while the photons continued to bounce around the room!

Absorption: Absorption, 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

en.wikipedia.org/wiki/Absorption_(chemistry)

Absorption is a condition in which something takes in another substance. In many processes important in technology, the chemical absorption is used in place of the physical process, e.g., absorption of carbon dioxide by sodium hydroxide – such acid-base processes do not follow the Nernst partition law.

Light absorption is a process by which light is absorbed and converted into energy. This process is known as photosynthesis in plants. However, light absorption doesn’t occur exclusively in plants, but in all creatures/inorganic substances. Absorption depends on the electromagnetic frequency of the light and object’s nature of atoms.
