    The figure indicates the energy level diagram of an atom and the origin of six spectral lines in emission (e.g. line no. 5 arises from the transition from level B to A). The following spectral lines will also occur in the absorption spectrum [CBSE PMT 1995]

    A)            1, 4, 6                                      

    B)            4, 5, 6

    C)            1, 2, 3                                      

    D)            1, 2, 3, 4, 5, 6

    Correct Answer: C

    Solution :

               The absorption lines are obtained when the electron jumps from ground state (n = 1) to the higher energy states. Thus only 1, 2 and 3 lines will be obtained.
