"hydrogen" nach Englisch mit Beispielen - Kollokationen-Wörterbuch Englisch
- The Niels Bohr model of the atom gave a very accurate explanation of the hydrogen spectrum, but when it came to helium, it collapsed.
- In contrast, there are also helium-weak B-type stars with understrength helium lines and strong hydrogen spectra.
- It then looks at the antihydrogen spectrum in order to compare it against "normal" hydrogen spectrum.
- When lines of the hydrogen spectrum are examined at very high resolution, they are found to be closely spaced doublets.
- The star has blurred lines in its hydrogen spectrum due to its rotation.
- It accounted for the fine details of the hydrogen spectrum in a completely rigorous way.
- Historically, explaining the nature of the hydrogen spectrum was a considerable problem in physics.
- Nobody could predict the wavelengths of the hydrogen lines until 1885 when the Balmer formula gave an empirical formula for the visible hydrogen spectrum.
- Later, it was discovered that when the spectral lines of the hydrogen spectrum are examined at very high resolution, they are found to be closely spaced doublets.
- Balmer noticed that a single number had a relation to every line in the hydrogen spectrum that was in the visible light region.
