Fraunhofer lines are dark absorption lines in the solar spectrum that can be seen when sunlight is passed through a prism to separate it into the colors of the rainbow. They occur because cooler gas, which is higher in the Sun's atmosphere, absorbs...

When a source (such as the sun) gives off light, that light can be dispersed into a rainbow spectrum by a prism or diffraction grating. If the light is pure white, the spectrum will contain all the colors of the spectrum. If, however, the light is not...

In physics and optics, the Fraunhofer lines are a set of spectral lines named for the German physicist Joseph von Fraunhofer (1787–1826). The lines were originally observed as dark features (absorption lines) in the optical spectrum of the Sun. The...

After establishing an arm in the strategically important U.S. market a few years ago, Germany's Fraunhofer Gesselschaft is now looking eastward to Russia for further expansion. Europe's largest center for applied research has opened a new office in Moscow in an effort to...
