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

Options

ABrackett series
BPaschen series
CLyman series
DBalmer series

Correct answer

D. Balmer series

Step-by-step solution

The transition from higher states to n = 2 lead to the emission of radiation with wavelengths 656 . 3   nm and 365 . 0   nm . These wavelengths fall in the visible region and constitute the Balmer series.
