Question

which spectral line appear in both emission and absorption spectrum of hydrogen?

Answer 1

Answer:

Lyman series

Explanation:

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 and then going on ....

here's the answer and hope this helps you.
