Question

Which among the following series is obtained in both absorption and emission spectrums?

• A. Lyman series
• B. Balmer series
• C. Paschen series
• D. Brackett series

Answer 1

The correct option is A Lyman series

Lyman series is obtained in both absorption and emission spectrums. Lyman series corresponds to transitions to $n=1$ level. Most of the time, the electron is present in the ground state only.
The remaining series are obtained in emission spectrum only.
Note:
Balmer series corresponds to transitions to $n=2$ level.
Paschen series corresponds to transitions to $n=3$ level.
Pfund series corresponds to transitions to $n=4$ level.
