Question 1.
What causes fine structure in atomic spectra?
Show hintHide hint
Think about the interactions involving electron spin and movement.
Question 2.
Define the Zeeman Effect.
Show hintHide hint
Consider how magnetic fields might influence light.
3Question 3.
What primarily causes fine structure in spectra?
- Spin–Orbit Coupling
- Zeeman Effect
- Stark Effect
Show hintHide hint
Look for the key interactions within an atom.
4Question 4.
True or False: Hyperfine structure is more significant than fine structure.
- True
- False
Show hintHide hint
Think about the scale of energy differences.
Question 5.
If the fine structure splitting in a specific atom is measured as 7 × 10^(-5) eV, and it is caused by spin-orbit coupling, how does this value compare with a typical hyperfine structure splitting? Discuss and calculate a ratio of fine to hyperfine structure if hyperfine is known to be around 1 × 10^(-6) eV.
Show hintHide hint
Use simple division to find the ratio.
Question 6.
Discuss how Zeeman and Stark effects would both impact observed spectral lines in a laboratory and a stellar environment. Provide potential observations from both environments.
Show hintHide hint
Consider the nature of external fields in both environments.
