Question

For the Paschen series the values of $n_{1}$ and $n_{2}$ in the expression $\Delta E=Rhc\left(\frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}}\right)$ are

A

$n_{1}=1, n_{2}=2,3,4 ........$

B

$n_{1}=2, n_{2}=3,4,5 ........$

C

$n_{1}=3, n_{2}=4,5,6 ........$

D

$n_{1}=4, n_{2}=5,6,7 ........$

Answer

$n_{1}=3, n_{2}=4,5,6 ........$

Explanation

Solution

Paschen series is the third series of hydrogen spectrum and lies in the infrared region, therefore for this series, $n_{1}=3$ and $n_{2}>n_{1}$ , ie, $4,5,6, \ldots$
