  1. Question 1

    Q1. Why does the Balmer series appear in the visible region of hydrogen's spectrum?

    • A) Transitions to n=2 release photons with visible frequencies.
    • B) The human eye is sensitive to transitions from n=2.
    • C) Atmospheric filtering isolates Balmer wavelengths.
    • D) n=2 is the ground state for visible transitions.

    Answer: Transitions to n=2 release photons with visible frequencies.

    Explanation: Energy differences for n=2 transitions correspond to visible light. Option D is wrong because n=1 is the true ground state.
