Question

Transition from $n=4,5,6$ to $n=3$ in hydrogen spectrum gives:

• A. Lyman series
• B. Balmer series
• C. Paschen series
• D. P fund series

Answer 1

Answer: (C)

For Paschen series in hydrogen spectrum the transition is as: $n_1=3$ and
$n_2=4,5,6,\dots .\infty$
$\frac{1}{\lambda }R\left[\frac{1}{3^2}-\frac{1}{n_2^2}\right]$
