    In the hydrogen spectrum, spectral lines which are emitted due to the jump of electron from a higher orbit to the innermost orbit, correspond in frequency to the region.

    A)  visible             

    B)  ultraviolet

    C)  infrared           

    D)  all of the above

    Correct Answer: B

    Solution :

    : Lyman series, falling in ultraviolet region, is produced when an electron jumps from higher orbit to the innermost orbit\[({{n}_{1}}=1)\]in hydrogen spectrum. A large energy is intact emitted in the transition. Hence the spectral lines have frequencies corresponding to ultraviolet region.
