  1. Question 1

    Q1. The frequency of a spectral line in the emission spectrum of hydrogen is 3.29 × 10^15 Hz. Identify the transition.

    • A) n=2 to n=1
    • B) n=3 to n=1
    • C) n=3 to n=2
    • D) n=4 to n=2

    Answer: n=2 to n=1

    Explanation: ΔE = hf, corresponds to Lyman-alpha line (n=2 to n=1). Option B is for a different frequency.
