D)Paschen, Balmer, Lyman.

Question

Quizplus · Accepted Answer

The spectral line series emitted by excited hydrogen atoms in order of increasing wavelength range is Lyman, Balmer, Paschen. This is because the Lyman series corresponds to transitions from higher energy levels to the n=1 level, the Balmer series corresponds to transitions to the n=2 level, and the Paschen series corresponds to transitions to the n=3 level. Since the energy of the n=1 level is the highest, the wavelengths of the spectral lines in the Lyman series are the shortest, and as the energy levels decrease, the wavelengths of the spectral lines increase. Therefore, the correct order is Lyman, Balmer, Paschen.
