  • question_answer
    Which of the following value of\[{{n}_{1}}\] in the relationship\[\frac{1}{\lambda }=R\left( \frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}} \right)\] is correct when\[{{n}_{2}}>{{n}_{1}}\]corresponds to Paschen lines in the hydrogen spectrum?

    A)  1                                            

    B)  2

    C)  3                                            

    D)  4

    Correct Answer: C

    Solution :

                     For Paschen series in hydrogen spectrum \[{{n}_{1}}=3,\text{ }{{\text{n}}_{2}}=4,\text{ }5,\text{ }6...\infty .\] \[\frac{1}{\lambda }=R\left( \frac{1}{{{3}^{2}}}-\frac{1}{n_{2}^{2}} \right)\]
