  1. Question 1

    Q1. The series limit of the Balmer series is given by 1 / λ = R * (1 / 2²). What is λ?

    • A) 364.6 nm
    • B) 486.1 nm
    • C) 656.3 nm
    • D) 410.2 nm

    Answer: 364.6 nm

    Explanation: 1 / λ = R * (1 / 2²) = R / 4. λ = 4 / R = 364.6 nm, using R = 1.097 * 10^7 m^-1.
