Question
**Understanding Electron Transitions in Hydrogen Atoms**

In this exercise, we'll examine the transitions between quantum energy levels in a hydrogen atom, specifically between the levels \( n = 1 \) through \( n = 4 \).

### Diagram Analysis:

- The diagram shows four horizontal lines representing energy levels.
- These levels are labeled from top to bottom as \( n = 4 \), \( n = 3 \), \( n = 2 \), and \( n = 1 \).
- Arrows pointing downwards indicate possible transitions of an electron moving to a lower energy level, which corresponds to emission of energy.

### Questions:

**a. How many emission lines are possible, considering only the four quantum levels?**

- To determine this, consider all possible transitions between these levels.

**b. Photons of the lowest energy are emitted in a transition from the level with \( n = \_\_\_\_ \) to a level with \( n = \_\_\_\_ \).**

- This involves the smallest difference in energy between two levels.

**c. The emission line having the shortest wavelength corresponds to a transition from the level with \( n = \_\_\_\_ \) to the level with \( n = \_\_\_\_ \).**

- This involves the largest energy difference between two levels.

Consider these principles:
- Larger energy differences result in shorter wavelengths.
- Smaller energy differences result in longer wavelengths.

By exploring these questions, you'll gain insights into the behavior of electrons in atoms and how they emit light at specific wavelengths.
