Atomic Structure: Practice Problem & Solution
When an electron do transition from $n = 4$ to $n = 2$, then emitted line in spectrum will be: (2000)
Solution Explained:
To solve this problem, we apply the core principles of Atomic Structure. Understanding the underlying formula is key to arriving at the correct answer below:
Transitions ending at $n=2$ belong to the Balmer series. The transition $n=3 \rightarrow 2$ is the first line, and $n=4 \rightarrow 2$ is the second line of the Balmer series.
