The spectral series which corresponds to the electronic transition from the levels n₂=5,6,… to the level n₁=4 is

Asked in Re-NEET 2024 · Spectral series and wavelengths

Answer: (2) Brackett series

Step-by-step solution

Lyman ends on n=1, Balmer on n=2, Paschen on n=3, Brackett on n=4, Pfund on n=5.

Transitions ending on n₁=4 form the Brackett series.
