Question

Which of the following statement regarding spectral series is correct?
  1. The lines in the Balmer series correspond to electron transitions from energy levels higher than n =1 energy level
  2. Paschen series appear in the infrared region
  3. The lines of Lyman series appear in the visible region
  4. Transitions from higher energy levels to the 4th energy level produce Pfund series which fall in the infrared region


Solution

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.
