Question

In the atomic spectrum of hydrogen, the spectral lines pertaining to electronic transition of $n = 4$ to $n = 2$ refers to

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

Hint:

Lyman: $n \rightarrow 1$, Balmer: $n \rightarrow 2$, Paschen: $n \rightarrow 3$, Brackett: $n \rightarrow 4$.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Spectral series in hydrogen correspond to transitions to different lower energy levels.
Step 2: Detailed Explanation:
Transitions to $n=2$ belong to the Balmer series.
Step 3: Final Answer:
The transition $n=4$ to $n=2$ belongs to the Balmer series.
