  1. Question 1

    Q1. The wavelength of a spectral line is given by 1 / λ = R * (1 / n1² - 1 / n2²). What is the value of n2 for the second line in the Lyman series?

    • A) 2
    • B) 3
    • C) 4
    • D) 5

    Answer: 3

    Explanation: The second line in the Lyman series corresponds to the transition from n = 3 to n = 1.
