The strong atmospheric extinction in some wavelength regions (such as X-ray, ultraviolet, and infrared) requires the use of space-based observatories.

In their native state, the bases of DNA absorb light in the 260-nm wavelength region.

Each observatory was designed to push the state of technology in its intended wavelength region.

Borosilicate glass retains useful transmission in this wavelength region, allowing large aperture optics to be produced at moderate cost.

Various factors in a chromophore's structure go into determining at what wavelength region in a spectrum the chromophore will absorb.

They alerted us to a particular wavelength region.

Traditional spectroscopic techniques have not been successful at doing this in natural gas because methane absorbs light in the same wavelength regions as water.

The eye contains several photostable pigments that all absorb in the short wavelength region, and hence contribute somewhat to the red eye effect.

However it provides the possibility for gain in different wavelength regions from the EDFA.

With light in this wavelength region, mostly only weak overtone transitions of molecules can be addressed.
