    Which of the following transitions in hydrogen atom produces longest wavelength of radiation (or photon of minimum energy)?

    A)  n = 2, p = 4     

    B)  n = 3, p = 4

    C)  n = 6, p = 8     

    D)  n = 5, p = 6

    Correct Answer: C

    Solution :

    Higher the value of the principle quantum number to which electron is jumping, longer will be the wavelength. So, n = 6, p = 8 transition produces longest wavelength.
