Question

When electron jumps from $n=4$ to $n=2$ orbit, we get,

• A. second line of Lyman series.
• B. second line of Balmer series.
• C. second line of Paschen series.
• D. an absorption line of Balmer series.

Answer 1

The correct option is B second line of Balmer series.

We know that, the emission of energy by an electron when it transits from $n=4$ to $n=2$ corresponds to the second line of Balmer series.

As for the second line in Balmer series, $n=4$ to $n=2$.

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