Thermal grating was generated after resonant absorption of light by the dye.

It is assumed that the emission and absorption of light energy by an atom or molecule is not a continuous precess but occurs in steps.

假定原子或分子发射光能和吸收光只能不是一个连续的过程，而是阶梯式发生的。

This paper gives the proof of this rule, and applies this rule to calculate the transition probability of the emission and absorption of light.

本文给出了这一规则的证明，并应用此规则计算了光的发射与吸收的跃迁几率。

And that sparse array of wires has exactly the same light absorption and electricity-collection properties as the conventional silicon wafer cell."

The audience becomes entranced precisely by the means of making the spectacle, an absorption that, aided by menacing sound and flashing light, focusses attention on the devastation of war and, by contrast, the horsiness of a horse the rearing, twitching, and nuzzling through which its nobility and affection pour out.

Here, plastics that are black to the eye actually reflect a reasonable amount of light, so it is possible to get a meaningful absorption spectrum.

Since atoms have well understood light absorption properties, predictions can be made about the depth of a shadow cast, improving communication between the individual atoms performing calculations.
