- Brackett series
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
- The hydrogen spectrum consists of several series: Lyman, Balmer, Paschen, Brackett, and Pfund.
- Among these, only the Balmer series falls in the visible region of the electromagnetic spectrum (wavelengths approximately 400–700 nm).
- The Balmer series corresponds to electron transitions ending at the second energy level ($n=2$).
