    The transition from the state \[n=4\] to \[n=3\] in a hydrogen-like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition         [IIT-JEE (Screening) 2001]

    A)            \[2\to 1\]                               

    B)            \[3\to 2\]

    C)            \[4\to 2\]                               

    D)            \[5\to 4\]

    Correct Answer: D

    Solution :

               As the transition \[n=4\]and \[n=3\], results in UV radiation and infrared radiation involves smaller amounts of energy UV. So we require a transition involving initial values of n greater than 4 e.g. \[5\to 4\].
