Calculate the wavelength of the spectral line in the spectrum of hydrogen when n=3 in Balmer formula.

Explanation

To calculate the wavelength of the spectral line in the spectrum of hydrogen when n=3 using the Balmer formula, follow these steps:

### Step 1: Understand the Balmer Series
The Balmer series describes the spectral lines of hydrogen when an electron transitions from a higher energy level (n2) to a lower energy level (n1). For the Balmer series, n1 is always 2.

### Step 2: Identify the Values
In this case, we have:
- n2 = 3 (the higher energy level)
