Show the `H_alpha` and `H_beta` transitions of hydrogen atom in an energy level diagram and find their wavelengths.

Explanation

To solve the question regarding the H_alpha and H_beta transitions of the hydrogen atom, we will follow these steps:

### Step 1: Energy Level Diagram
1. **Draw the Energy Levels**: The energy levels of the hydrogen atom can be represented as horizontal lines. The ground state (n=1) is at the bottom, followed by n=2, n=3, and n=4, etc.
- Label the energy levels:
- n=1 (Ground state)
- n=2
- n=3
