### Constants needed for the calculations:
- \( c = 3.00 \times 10^8 \, \text{meters/second} \)
- Planck's Constant (\( h \)) = \( 6.63 \times 10^{-34} \, \text{joules seconds} \)
- \( n_f = 2 \)

### Table of Wavelengths and Calculations:

|                      | Red Light     | Green Light   | Blue Light    | Violet Light  |
|----------------------|---------------|---------------|---------------|---------------|
| **Wavelength (nm)**  | 656.2 nm      | 486.1 nm      | 434.0 nm      | 410.0 nm      |
| **Wavelength (m)**   |               |               |               |               |
| **ΔE (J)**           |               |               |               |               |
| **\( n_i \)**             |               |               |               |               |

#### Explanation:

This table presents wavelengths for different colors of light:

- **Red Light**: 656.2 nanometers (nm)
- **Green Light**: 486.1 nanometers (nm)
- **Blue Light**: 434.0 nanometers (nm)
- **Violet Light**: 410.0 nanometers (nm)

### To Be Calculated:

1. **Wavelength (m)**: Convert the wavelength from nanometers (nm) to meters (m).
2. **ΔE (J)**: Calculate the energy difference using the given constants.
3. **\( n_i \)**: Determine initial quantum number based on given final quantum number (\( n_f = 2 \)).

### Conversion and Calculation Steps:

1. **Convert Wavelength (nm) to Wavelength (m)**:
   - \( \text{Wavelength (m)} = \text{Wavelength (nm)} \times 10^{-9} \)

2. **Calculate Energy (ΔE in J)** using the formula:
   - \( \Delta E = h \times \frac{c}{\text{Wavelength (m)}} \)

3. **Determine Initial Quantum Number (\( n_i \))**:
   - Use appropriate quantum mechanical equations to find \( n_i \) based on energy levels and \( n_f \).

This structured information helps students understand the relationships between wavelength, energy, and quantum numbers
