  1. Question 1

    Q1. What causes the fine structure in hydrogen's spectral lines?

    • A) Electron spin-orbit coupling and relativistic effects.
    • B) Vibrational energy levels of atomic hydrogen.
    • C) Collisional broadening in high-pressure environments.
    • D) Nuclear magnetic interactions with electrons.

    Answer: Electron spin-orbit coupling and relativistic effects.

    Explanation: Fine structure arises from relativistic corrections and spin-orbit interactions. Option D refers to hyperfine structure instead.
