### The Photoelectric Effect

#### Question:
What process describes the phenomenon of light hitting a material and producing electricity?

#### Options:
- Photoelectric effect
- Electromagnetism
- Charging
- Static electricity

---

### Diagram Explanation:

The image above features a diagram demonstrating the photoelectric effect. 

1. **Red Wavy Lines:** These illustrate the light, which is comprised of photons, striking the surface of a material.
2. **Black Circle Symbols on Rectangular Surface:** Represent electrons within the material.
3. **Blue Arrows:** Indicate the movement of the ejected electrons, showing their transition from the material into the space above it.

When the photons (light) strike the surface, they impart energy to the electrons in the material. If the energy from the photons is sufficient, it causes some of the electrons to be ejected from the material's surface. This ejection of electrons due to light exposure is known as the photoelectric effect, which is the correct answer to the question posed at the top of the image.

The photoelectric effect is a fundamental concept in quantum mechanics and has important implications in various scientific fields, including the development of photovoltaic cells for solar power.
