The angle of reflection is the angle between:

Options

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

Answer

To solve the question regarding the angle of reflection, we need to understand the definitions and relationships involved in the reflection of light.

### Step-by-Step Solution:

1. **Understanding Reflection**:
- When a light ray strikes a surface (like a mirror), it is called the incident ray. The ray that bounces off the surface is called the reflected ray.

2. **Identifying the Normal**:
- The normal is an imaginary line that is perpendicular to the surface at the point where the incident ray strikes. This line is crucial for measuring angles related to reflection.

3. **Defining Angles**:
- The angle of incidence (I) is the angle between the incident ray and the normal.
- The angle of reflection (R) is the angle between the reflected ray and the normal.

4. **Correct Definition of Angle of Reflection**:
- The angle of reflection is specifically defined as the angle formed between the normal to the surface of the mirror and the reflected ray.

5. **Conclusion**:
- Therefore, the correct answer to the question is that the angle of reflection is the angle between the normal to the surface of the mirror and the reflected ray.

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