Does zeeman effect prove that there are high magnetic fields in sunspots?

Observations show that the spectral lines of light from sunspots are split. This is consistent with them having high magnetic fields (and it's even possible to estimate how high by the degree of splitting), because that's what the Zeeman effect is: the splitting of electronic energy levels (which in turn affects the spectrum of transitions involving those energy levels) by an external magnetic field.
The effect itself doesn't directly have anything to do with sunspots particularly, and I'm not certain that I'd use the word prove, but the splitting combined with knowledge of the Zeeman effect is pretty substantial evidence that sunspots are correlated with magnetic flux.

Why splitting of spectral lines take place in magnetic field?
The Zeeman Effect
Is NMR a solvent extraction technique?
NMR stands for Nuclear Magnetic Resonance. It's an analytical/spectrographic technique based on the Zeeman effect.
Can astronomers learn the magnetic field of a star?
Light that comes from the sun is polarized by these magnetic fields. A meter can determine the different directions of the light and detect interference. This interference is known as a magnetic field.
Quantum mechanical treatment of zeeman effect?
Quantum mechanics describes the Zeeman effect as the splitting of energy leves. It is caused by the so called "m" quantum number. This effectively quantises the orientation of the electrons orbit. m can take values from -n to n where n is the principle quantum number. for example if n = 1 then m = -1,0,1. The n=1, m = -1 and the n=1, m=0 quantum staes have slightly different energies and this leads to the splitting of the energy levels as observed by 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.
Sunspots are known to be magnetic phenomena because?
Sunspots are known to be magnetic phenomena because of the Zeeman effect. The Zeeman effect has been found in sunspots.
What is the zeeman effect?
The Zeeman effect is the splitting of single spectral lines into three or more in the presence of a magnetic field.
Differences between anomalous zeeman effect and normal?
normal zeeman effect occurs in strong magnetic field while anamolous zeeman effect occur in weak magnetic field
What does zeeman effect mean?
The splitting of single spectral lines of an emission or absorption spectrum of a substance into three or more components when the substance is placed in a magnetic field. The effect occurs when several electron orbitals in the same shell, which normally have the same energy level, have different energies due to their different orientations in the magnetic field. A normal Zeeman effectis observed when a spectral line of an atom splits into three lines under a magnetic field. An anomalous Zeeman effectis observed if the spectral line splits into more than three lines. Astronomers can use the Zeeman effect to measure magnetic fields of stars. Compare Stark effect.
Why splitting of spectral lines take place in magnetic field?
The Zeeman Effect
What is a Zeeman slower?
A Zeeman slower is a system which allows the cooling of atoms to temperatures of a few kelvins, based on the principle that a magnetic field can change the resonance frequency of an atom using the Zeeman effect.
Describe about zeeman and stark effect?
zeeman efeect is splitting of a single spectral line into multiple ones in the pressence of a magnetic filed and stark effest ,the same only takes place in an electrical field.
Is NMR a solvent extraction technique?
NMR stands for Nuclear Magnetic Resonance. It's an analytical/spectrographic technique based on the Zeeman effect.
What is produced by atomic transitions in the presence of a strong magnetic field?
Iron, nickel and cobalt are magnetic transition metals.
What has the author Alan George Brown written?
Alan George Brown has written: 'Nuclear magnetic and Zeeman quadrupole resonance' -- subject(s): Quadrupole moments, Nuclear magnetic resonance, Physics Theses, Zeeman effect 'Introduction to subject indexing' -- subject(s): Programmed instruction, Subject cataloging, Indexing
Why is the zeeman effect used by astronomers?
It's used to determine the magnetic field strength of stars. That's not really a "why", though. I suppose the "why" would be "because they want to know the magnetic field strength of stars".
Can astronomers learn the magnetic field of a star?
Light that comes from the sun is polarized by these magnetic fields. A meter can determine the different directions of the light and detect interference. This interference is known as a magnetic field.
