  1. Question 1

    Q1. The series limit of the Balmer series is at λ = 364 nm. What is the series limit of the Lyman series?

    • A) 91 nm
    • B) 121 nm
    • C) 102 nm
    • D) 122 nm

    Answer: 91 nm

    Explanation: Using the Rydberg formula, the series limit for Lyman series corresponds to n = ∞ to n = 1, 1 / λ = R, λ = 1 / R = 91 nm.
