Question

Which series of line spectrum of H-atom is observed usually in both emission and absorption spectrum?

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

Answer 1

The correct option is A Lyman

Usually, all atoms have electron in ground state and when they get energy and give absorption spectrum, Lyman series occurs.

So, Lyman series is present in both absorption and emission spectrum.

Hence, option $\left(A\right)$ is the correct answer.
