  1. Question 1

    Q1. A physicist examines the Paschen-Back effect in molecular spectra. Which phenomenon does the Paschen-Back effect involve?

    • A) Splitting of spectral lines due to external magnetic field
    • B) Merging of spectral lines due to strong magnetic field
    • C) Broadening of spectral lines due to Doppler effect
    • D) Shift of spectral lines due to temperature change

    Answer: Merging of spectral lines due to strong magnetic field

    Explanation: The Paschen-Back effect is a merging of spectral lines due to a strong external magnetic field, not the other options.
