    The transition from the state n = 3 to n = 1 in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition.

    A) \[2\to 1\]                       

    B) \[3\to 2\]  

    C) \[4\to 2\]                       

    D) \[4\to 3\]

    Correct Answer: D

    Solution :

    \[{{\operatorname{n}}_{1}}=1, {{n}_{2}}, =2, 3, 4\ldots \ldots \]           Ultraviodet \[{{\operatorname{n}}_{1}}=2, {{n}_{2}}, =3, 3, 4,\ldots \ldots \]                      Visible \[{{\operatorname{n}}_{1}}=3, {{n}_{2}}, =4, 5\ldots \ldots \]               Infrared \[{{\operatorname{n}}_{1}}=4, {{n}_{2}}, =5, 6\ldots \ldots \]               Infrared \[{{\operatorname{n}}_{1}}=5, {{n}_{2}}, =6, 7,\ldots \ldots \]              Infrared \[\operatorname{transition} 4\to 3\]                      Infrared
