What are vertical lines called?
They are simply just called lines.
What are two coplanar lines that never intersect called?
Two coplanar lines that never intersect are called called parallel lines.
What are straight lines that never cross called?
Straight lines that never cross are called parallel lines.
If two lines in the same plane and do not intersect they are called?
Coplanar lines that do not intersect are parallel. Non-coplanar lines that do not intersect are called skew lines.
Are parallel lines also called skew lines?
No. Skew lines are lines in different planes that are parallel.
Why splitting of spectral lines take place in magnetic field?
The Zeeman Effect
What are the dark lines in a stellar spectrum are called?
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.
Who introduced the concept of elliptical orbits to explain the splitting of the spectral lines?
Arnold Sommerfeld
Can the Doppler effect reveal the rotation speed of a star by the splitting of the spectral lines?
Yes that is true! Astronomy homework?
What are dark lines in a stellar spectrum called?
The dark lines are absorption spectrum, the energy absorbed by Atoms in the atmosphere of the star. ================================ Fraunhofer's spectral lines.
The spectral lines from distant galaxies do not match spectral lines on Earth due to?
wavelength shift
The spectrum of a star is called a what?
... a photonic 'fingerprint'. The picture of a star's spectral lines is its photo-spectrograph.
Spectral lines are of particular importance in astronomy because?
For one reason, astronomers can figure out what stars are composed of by looking at their spectral lines.
Why did Johannes Stark win The Nobel Prize in Physics in 1919?
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.
Quasars have what kind of spectral lines?
Quasars have all kinds of spectral lines namely more energetic ones which makes them the brightest objects in the night sky.
Why would the star Sirius find that its spectral lines are blue shifted?
The spectral lines of Sirius are blueshifted because the star is moving more or less toward us.
Does Every element and compound in nature have a unique set of spectral lines?
Elements have several spectral lines and although some lines may be the same between different elements most lines are not and the whole spectrum for each element is indeed unique.
