Vedclass · Answer

(C) The spectral series of hydrogen are defined by the lower energy level $n_2$ to which the electron transitions from higher levels $n_1$:$n_2 = 1$ (Lyman series): Ultraviolet region.$n_2 = 2$ (Balmer series): Visible region.$n_2 = 3$ (Paschen series): Infrared region.$n_2 = 4$ (Brackett series): Infrared region.$n_2 = 5$ (Pfund series): Infrared region.Since the question refers to transitions to $n = 3, 4, 5$,all these series (Paschen,Brackett,and Pfund) fall within the Infrared region.

Identify the region of the electromagnetic spectrum for the spectral lines when electron transition takes place from higher energy levels to $n=3, 4, 5$ in the atomic spectrum of hydrogen.
