Draw energy level diagram for Hydrogen atom showing at least four lowest energy levels. Show the transitions responsible for emission of Balmer series.

Explanation

To draw the energy level diagram for a hydrogen atom showing at least four lowest energy levels and the transitions responsible for the emission of the Balmer series, follow these steps:

### Step 1: Draw the Energy Levels
1. **Identify the Energy Levels**: The energy levels for the hydrogen atom are given by the formula:
\[ E_n = -\frac{13.6 \, \text{eV}}{n^2} \]
where \( n \) is the principal quantum number (1, 2, 3, 4, ...).
