Question:medium

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

Updated On: Jan 13, 2026
  • Pfund series
  • Brackett series
  • Lyman series
  • Balmer series
Show Solution

The Correct Option is B

Solution and Explanation

Electronic transitions terminating at the n1 = 4 energy level, with initial states from n2 = 5, 6, 7, and so on, define the Brackett series.
