Question
**Energy Levels and Photon Absorption/Emission in Atoms**

This educational content presents an energy diagram illustrating the allowed energy levels of an electron within a specific atom. These energy levels are measured in zeptojoules (zJ), where the SI prefix 'zepto' denotes \(10^{-21}\).

**Diagram Explanation:**

- The vertical axis represents energy in zeptojoules (zJ).
- There are three labeled energy levels:
  - Level A at approximately 400 zJ.
  - Level B at approximately 600 zJ.
  - Level C at approximately 800 zJ.
- A red arrow indicates a transition from level A to level B.

**Table Completion Instructions:**

Use the diagram to answer the following:

1. **Ground State Energy:**
   - What is the energy of the electron in the ground state? 
   - Answer: ____ zJ

2. **First Excited State Energy:**
   - What is the energy of the electron in the first excited state? 
   - Answer: ____ zJ

3. **Photon Absorption/Emission:**
   - If the electron transitions as shown by the red arrow, from A to B, will a photon be absorbed or emitted? 
   - Options: absorbed / emitted

4. **Photon Wavelength Calculation:**
   - Calculate the wavelength of the photon that would be absorbed or emitted. Round your answer to 3 significant digits.
   - Answer: ____ nm
