Joseph Von Fraunhofer as a German physicist who independently discovered (or rediscovered) dark "lines" in the emission spectra of the light emitted by the Sun. Fraunhofer carefully cataloged the precise frequencies of the light that was NOT being emitted by the Sun.
Many years later, two other scientists realized that these colors of light were associated with the spectra of particular elements present in the Sun.
The English chemist William Hyde Wollaston was in 1802 the first person to note the appearance of a number of dark features in the solar spectrum. In 1814, the German physicist Joseph von Fraunhofer independently rediscovered the lines and began a systematic study and careful measurement of the wavelength of these features.
The dark lines represents the absorption of energy at that frequency, E=hf.
Anything that can reflect light is only visible to an eye... others which cannot are dark..
If your talking about WoWP then you are exactly right it's called Wizards vs. Angles
I got the key of darkness in Grand Chokmah. i dont remember exactly when though. Sorry... It's a small event with the dark wings.
The main antagonist of the Harry Potter Series is Lord Voldemort aka The Dark Lord, He-Who-Must-Not-Be-Named, You-Know-Who, and Tom Marvolo Riddle.
Dark lines especially in solar spectrum have been named as Fraunhofer lines. These line are good examples for line absorption spectrum
Atoms in the atmosphere of the star is responsible for the dark lines in its spectrum.
dark-line spectrum...
The dark lines are absorption spectrum, the energy absorbed by Atoms in the atmosphere of the star. ================================ Fraunhofer's spectral lines.
No. You're thinking of Fraunhofer. A natural slip for English speakers.
Absorption lines
absorption lines! :)
The dark lines represents the absorption of energy at that frequency, E=hf.
Because the spectrum of the star's light can be seen to have dark lines all the way through, and each element has its own set of dark lines in the star's spectrum.
The dark lines reveal the atoms that are associated with the stars atmosphere. The dark lines are atom energy absorption signatures.

Band spectrum is the spectrum given by the molecules. It consists of series of closely spaced lines known as bands separated by the dark spaces.
