The atomic hydrogen emits a line spectrum consisting of various series. Which series of hydrogen atomic spectra is lying in the visible region?

1. Brackett series
2. Paschen series
3. Lyman series
4. Balmer series

Correct answer: Balmer series

Solution

The Balmer series corresponds to electron transitions from higher energy levels to the second energy level, resulting in the emission of visible light, which is why it is the only series among the options that lies in the visible region of the spectrum.
