Question

Which of the following statement regarding spectral series is correct?

• A. The lines in the Balmer series correspond to electron transitions from energy levels higher than n =1 energy level
• B. Paschen series appear in the infrared region
• C. The lines of Lyman series appear in the visible region
• D. Transitions from higher energy levels to the 4th energy level produce Pfund series which fall in the infrared region

Answer 1

The correct option is B Paschen series appear in the infrared region

Balmer series corresponds to transitions higher than n = 2
The lines of Lyman series appear in the UV region
Transition n = 4 corresponds to Brackett series
Hence only statement B is correct.
