# A student investigates how different regions of the electromagnetic spectrum interact with matter. The student considers three processes, each induced by the absorption of a single photon:

| Process | Phenomenon Induced by Photon Absorption |
| :— | :— |
| Process 1 | Ejection of an inner-shell (core) electron from an atom |
| Process 2 | Increase in the vibrational motion (stretching) of a covalent bond |
| Process 3 | Increase in the rotational motion of a molecule |

Which of the following correctly ranks the minimum photon energy required to induce each process, from greatest to least?

A student investigates how different regions of the electromagnetic spectrum interact with matter. The student considers three processes, each induced by the absorption of a single photon:

| Process | Phenomenon Induced by Photon Absorption |
| :--- | :--- |
| Process 1 | Ejection of an inner-shell (core) electron from an atom |
| Process 2 | Increase in the vibrational motion (stretching) of a covalent bond |
| Process 3 | Increase in the rotational motion of a molecule |

Which of the following correctly ranks the minimum photon energy required to induce each process, from greatest to least?

- **A.** \(\text{Process 1} > \text{Process 2} > \text{Process 3}\)
- **B.** \(\text{Process 1} > \text{Process 3} > \text{Process 2}\)
- **C.** \(\text{Process 2} > \text{Process 1} > \text{Process 3}\)
- **D.** \(\text{Process 3} > \text{Process 2} > \text{Process 1}\)
