Calculate the wave number and wave length of `H_(alpha)` line in the Balmer series of hydroge emission spectrum.

Explanation

To calculate the wave number and wavelength of the H-alpha line in the Balmer series of the hydrogen emission spectrum, we can follow these steps:

### Step 1: Identify the Transition Levels
The H-alpha line corresponds to the transition from n=3 to n=2 in the Balmer series. Here, n1 = 2 and n2 = 3.

### Step 2: Use the Rydberg Formula
The wave number (ν) can be calculated using the Rydberg formula:
\[
