The absorption spectra of the three systems overlap, and combine to cover the visible spectrum.

There are a wide range of experimental approaches to measuring absorption spectra.

The absorption spectrum is primarily determined by the atomic and molecular composition of the material.

Therefore, measurements of the absorption spectrum are used to determine these other properties.

The two measured spectra can then be combined to determine the material's absorption spectrum.

But if you don't know what an absorption spectrum is, or why it's significant - then you can't really understand either sides of the argument.

"I think we'll be lucky to get enough ablation for an absorption spectrum."

What does the absorption spectrum look like for these coatings?

He found that roughly a third of them had the absorption spectra of a gas.

Usually a moderate offset is kept within the absorption spectrum.
