Instead, they emit photons in a range of wavelengths. Scientists use what is known as a blackbody curve graph to plot out the wavelengths of light emitted by an object on a color spectrum. While a ...

The shape of the spectrum of this kind of radiation has a special form known as blackbody radiation. When it was emitted the temperature of the Universe was almost 3,000 degrees Centigrade.

However, the degree of narrowing was limited to about half of the blackbody spectrum, and it is important for a number of applications to realize an even narrower emission bandwidth while also ...
