engineering physics MCQ #561

  1. Question 1

    Q1. The energy of the photon emitted when an electron jumps from n = 3 to n = 1 in hydrogen atom is

    • A) 12.09 eV
    • B) 12.75 eV
    • C) 1.89 eV
    • D) 10.2 eV

    Answer: 12.09 eV

    Explanation: Using the energy level formula, E_n = -13.6 / n², we find the energy difference between n = 3 and n = 1 to be 12.09 eV.
