Which of the following statements regarding spectral series is correct? 

Options

A. The lines in the Balmer series correspond to the electronic transition from higher energy level to n = 1 energy level.
B. Paschen series appears in the infra-red-region
C. The lines of Lyman series appear in the visible region
D. Transition from higher energy levels to `4^(th)` energy level produces Pfund series which fall in the infrared region.

Answer

B

Explanation

Balmer `n_1=2` , Lyman = UV region , Pfund `n_1=5`
