  1. Question 1

    Q1. The frequency of the first line of Lyman series is given by f = ΔE / h. The value of f is

    • A) 2.46 * 10¹⁵ Hz
    • B) 3.08 * 10¹⁵ Hz
    • C) 1.89 * 10¹⁵ Hz
    • D) 2.92 * 10¹⁵ Hz

    Answer: 2.46 * 10¹⁵ Hz

    Explanation: ΔE = -13.6 * (1 - 1/4), f = ΔE / h = 2.46 * 10¹⁵ Hz.
