MDCAT Physics MCQ #266

  1. Question 1

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

    • A) 1/λ = R(1/1^2 - 1/3^2)
    • B) 1/λ = R(1/2^2 - 1/3^2)
    • C) 1/λ = R(1/3^2 - 1/1^2)
    • D) 1/λ = R(1/1^2 - 1/2^2)

    Answer: 1/λ = R(1/1^2 - 1/3^2)

    Explanation: Transition is from n=3 to n=1; option D is incorrect because it's for the first line of Lyman series (n=2 to n=1).
