engineering physics MCQ #556

  1. Question 1

    Q1. The energy of the photon emitted when an electron jumps from n = 3 to n = 2 in hydrogen atom is

    • A) 1.89 eV
    • B) 1.51 eV
    • C) 2.55 eV
    • D) 0.66 eV

    Answer: 1.89 eV

    Explanation: Using the energy level formula, E_n = -13.6 / n², we find the energy difference between n = 3 and n = 2 to be 1.89 eV.
