Because the electron volt energies limited our significant figures, we can only use our answer to THREE significant figures. Use 4.17 x 10 J for the calculation below. Part C- Now that you have the energy of the photon in Joules, use the equation to the left to calculate the wavelength (in nm) of this transition (n=4 to n=2). Report your answer to three significant figures.

The eV is 4.17x10^-19 J. It is also in the image below.
![### Photon Energy and Wavelength Calculation
#### Step 1: Energy Calculation
**Energy of the Photon (E<sub>photon</sub>):**
\[ E_{\text{photon}} = 4.17 \times 10^{-19} \, \text{J} \]
- **Significance:** The energy of the photon is calculated in joules and rounded to three significant figures. This precision is based on the limitations of electron volt energies.
#### Step 2: Wavelength Calculation
**Objective:** With the energy of the photon now known, calculate the corresponding wavelength (in nanometers) for a transition from \(n=4\) to \(n=2\).
- **Reported Wavelength:**
\[ 4.75 \times 10^{-7} \, \text{nm} \]
- **Note:** Ensure to report your answer to **three significant figures**.
#### User Interface Features:
- **Submit and Correction System:**
- Submissions are evaluated for correctness.
- Users can view previous answers and request solutions.
- **Guidance Note:**
- A message prompts the user to ensure answers are entered with the correct number of significant figures.
- **Feedback:**
