Question
### Photon Energy and Emission Spectrum #### Photon Energy Calculation **Scenario:** When a red light with a wavelength of 670 nm shines on a piece of metal, an electron is ejected. We need to determine the energy of the photon absorbed by the electron to overcome the attractive forces. **Options:** - 4.7 × 10⁻³⁵ J - 4.3 × 10⁻³⁷ J - **3.3 × 10⁻¹⁹ J** (correct answer) - 3.0 × 10⁻¹⁹ J - 2.9 × 10⁻³⁷ J #### Emission Spectrum Analysis **Details:** Below is an emission spectrum with two specific lines labeled 1 (orange) and 2 (green). **Diagram:** A spectrum is shown with a range from red to violet, containing two specific lines: - Line 1: Orange - Line 2: Green **Question:** Which energy level diagram best represents the labeled electronic transitions? **Diagrams:** 1. **Diagram A:** - Lines show two upward transitions; green from lowest to third level, orange from lowest to second level. 2. **Diagram B:** - Lines show one upward and one downward transition; orange upward from second lowest to mid-level, green downward from second highest to lowest level. 3. **Diagram C:** - Lines show two downward transitions; orange from second highest to mid-level, green from highest to lowest level. 4. **Diagram D:** - Lines show an upward and downward transition; orange from mid-level to second highest, green from highest to second lowest. **Correct Answer:** - **Diagram B** (upward orange transition, downward green transition)
