Find the wavelengths in a spectrum of hydrogen atom between 600 nm to 700 nm

Explanation

To find the wavelengths in the spectrum of a hydrogen atom between 600 nm to 700 nm, we will follow these steps:

### Step 1: Understand the Energy Levels of Hydrogen
The energy levels of a hydrogen atom can be calculated using the formula:
\[ E_n = -\frac{13.6 \, \text{eV}}{n^2} \]
where \( n \) is the principal quantum number (1, 2, 3, ...).

### Step 2: Calculate the Energy Levels
