  1. Question 1

    Q1. The ratio of the energies of the first excited state and the ground state of hydrogen atom is

    • A) 1 / 4
    • B) 1 / 9
    • C) 1 / 2
    • D) 3 / 4

    Answer: 1 / 4

    Explanation: Calculate E1 and E2 using En = -13.6 / n² eV, then find the ratio: E2 / E1 = (-3.4) / (-13.6) = 1/4.
