If, however, an appropriate luminescent pigment absorbs daylight in a special region of its spectrum, it can emit light of a colour different from that of the reflected light.
EE, created through the merger of the Orange and T-Mobile networks, was under order from regulators to sell off some of its spectrum as it held so much more than competitors.
He said it was likely that the F.C.C. was requiring Verizon to unload some of its spectrum before it could obtain the licenses from the cable companies just to ensure it did not have too much.

The radio characteristics of its spectrum make it more expensive to put to use.
"It's inevitable that they will eventually have to put caps (on their data use)." Sprint, which is spending $7 billion to upgrade its network to LTE by the end of 2013, says concerns about its capacity are overblown, arguing that advanced technology allows it to make the most of its spectrum resources.
Cesium (Cs), also spelled caesium, chemical element of Group 1 (also called Group Ia) of the periodic table, the alkali metal group, and the first element to be discovered spectroscopically (1860), by German scientists Robert Bunsen and Gustav Kirchhoff, who named it for the unique blue lines of its spectrum (Latin caesius, "sky-blue").
Any idea may be brought forth, but only if it's the most extreme version of its spectrum.
We show that a C*-algebra A has the weak Banach-Saks property if and only if it is type I and the kth-derivative of its spectrum  is empty for some k.
Northcoast is now exploring the sale of many of its spectrum licenses.
A standard candle can be identified by means of its spectrum or the pattern of regular variations in brightness.
