Sentences with phrase «selective absorption»

Dust is aligned in space to some extent, and this results in selective absorption such that there is a preferred plane of vibration for the light waves.

One major simplification involves treating all the infrared radiation (IR) as if it consisted of one wave length, although the real situation is of course much more complicated with a wave spectrum, selective absorption bands, and radiation with different frequencies and optical depths (Pierrehumbert 2011).

After ruling out the possibility that the helium may be doubly ionized, the authors conclude that the most likely explanation for the discrepancy is selective absorption of helium - ionizing photons by dust.

Then on subsequent passes of the laser, the selective absorption of infrared light turns the amorphous carbon into LIG.

«It opens the doors to using hydrogen bonds to make surfaces hydrophilic, or attracted to water, and to (template) these surfaces for the selective absorption of other molecules possessing fundamental similarities to water,» Mavrikakis says.

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.

Functions of epithelial cells include secretion, selective absorption, protection, trans - cellular transport and selective permeability.

A spectrophotometer allows for the measurements of concentration of multiple ions, compounds and large molecules based on the selective absorption of particular wavelengths of light.

Color is the selective absorption and emission of light on the surface of an object.

It also seems that even though the selective absorption of specific energy bands by different molecules IS the mechanism to add energy to the air, the energy absorbed by CO2 & especially Water Vapor is extremely rapidly dispersed by molecular collisions to ALL the components of the atmosphere, so that the N2 and O2 also heatup, and all the atmospheric components assume a uniform temperature (ie global warming).
