Q. An electron in excited hydrogen atom falls from fifth energy level to second energy level. In which of the following regions, the spectral line will be observed and is part of which series of the atomic spectrum?

Structure of Atom

Solution:

For Balmer series, $n_1 = 2$, $n_2 = 3$, $4$, $5$, $....$
The spectral lines are seen in visible region.
