MDCAT Physics MCQ #258

  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) 2.55 eV
    • C) 3.4 eV
    • D) 4.08 eV

    Answer: 1.89 eV

    Explanation: Energy difference between n=3 and n=2 is 1.89 eV; option B is incorrect because it's the energy difference between n=4 and n=2.
