They are simply just called lines.
Two coplanar lines that never intersect are called called parallel lines.
Straight lines that never cross are called parallel lines.
Coplanar lines that do not intersect are parallel. Non-coplanar lines that do not intersect are called skew lines.
No. Skew lines are lines in different planes that are parallel.
The Zeeman Effect
Fraunhofer realised that some of these dark lines were at the same position in effect called the Zeeman effect can also cause splitting of the spectral lines.
Arnold Sommerfeld
Yes that is true! Astronomy homework?
The dark lines are absorption spectrum, the energy absorbed by Atoms in the atmosphere of the star. ================================ Fraunhofer's spectral lines.
The Zeeman effect refers to the splitting of spectral lines in the presence of a magnetic field. It occurs because the magnetic field causes the energy levels of electrons in atoms to shift, leading to the splitting of spectral lines into multiple components. This effect is commonly observed in the spectra of atoms, ions, and molecules.
... a photonic 'fingerprint'. The picture of a star's spectral lines is its photo-spectrograph.
The spectral lines from distant galaxies do not match those on Earth because of the Doppler effect, cosmic expansion, and differences in elements present in the galaxies. These factors cause the observed spectral lines to be shifted or altered compared to what we see on Earth.
The Nobel Prize in Physics 1919 was awarded to Johannes Stark for his discovery of the Doppler effect in canal rays and the splitting of spectral lines in electric fields.
Beryllium spectral lines are specific wavelengths of light emitted or absorbed by beryllium atoms when they undergo transitions between energy levels. These spectral lines are unique to beryllium and can be used in spectroscopic analysis to identify the presence of beryllium in a sample.
Quasars have all kinds of spectral lines namely more energetic ones which makes them the brightest objects in the night sky.
The spectral lines of Sirius are blueshifted because the star is moving more or less toward us.
