Which of the following is called the angle of reflection?

Options

A. Angle between the normal and the incident ray.
B. Angle between the normal and the reflected ray.
C. Angle between the incident ray and the reflected ray.
D. Angle between the reflected ray and the surface of the mirror.

Answer

To determine which of the following is called the angle of reflection, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Reflection**:
- When light strikes a surface, it can bounce back. This phenomenon is known as reflection.

2. **Identifying the Surface**:
- For clear reflection, we need a smooth and polished surface, like a plain mirror.

3. **Defining the Normal**:
- At the point where the light ray strikes the mirror, we draw a perpendicular line to the surface of the mirror. This line is called the "normal."

4. **Incident Ray**:
- The incoming ray of light that strikes the mirror is called the "incident ray."

5. **Angle of Incidence**:
- The angle formed between the incident ray and the normal is known as the "angle of incidence."

6. **Reflected Ray**:
- After striking the surface, the light ray bounces back. This outgoing ray is called the "reflected ray."

7. **Angle of Reflection**:
- The angle formed between the reflected ray and the normal is called the "angle of reflection."

8. **Conclusion**:
- Therefore, the angle of reflection is defined as the angle between the normal and the reflected ray.

### Final Answer:
The angle of reflection is the angle between the normal and the reflected ray.
