MDCAT Physics MCQ #262

  1. Question 1

    Q1. The frequency of the photon emitted when an electron jumps from n=4 to n=3 in hydrogen atom is given by

    • A) f = (E4 - E3)/h
    • B) f = (E3 - E4)/h
    • C) f = E4/h
    • D) f = E3/h

    Answer: f = (E4 - E3)/h

    Explanation: Frequency is given by f = (E4 - E3)/h; option B is incorrect because energy difference should be positive.
