  1. Question 1

    Q1. The wavelength of the first line of Lyman series is 1216 Å. What is the wavelength of the second line?

    • A) 1026 Å
    • B) 1216 Å
    • C) 6563 Å
    • D) 4861 Å

    Answer: 1026 Å

    Explanation: Using 1/λ = R * (1/1² - 1/n²), for n = 3, 1/λ = R * (1 - 1/9), λ = 1026 Å.
