  1. Question 1

    Q1. What determines the spacing between spectral lines in the Paschen series?

    • A) Transitions to n=3 from higher energy levels.
    • B) Temperature of the emitting gas.
    • C) Pressure of the surrounding medium.
    • D) Atomic collisions in the sample.

    Answer: Transitions to n=3 from higher energy levels.

    Explanation: Energy gaps between states define line spacing. Option B affects line broadening, not spacing.
