Which transition between Bohr orbits corresponds to third line in the Balmer series of the hydrogen spectrum

Explanation

To determine which transition between Bohr orbits corresponds to the third line in the Balmer series of the hydrogen spectrum, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Balmer Series**: The Balmer series corresponds to transitions of an electron in a hydrogen atom from higher energy levels (n ≥ 3) to the second energy level (n = 2).

2. **Identify the Lines in the Balmer Series**: The lines in the Balmer series are defined by the transitions:
- First line: n = 3 to n = 2
