Reflection of light at a surface, illustrating the angle of incidence and angle of reflection.

Problem Analysis:

The image depicts a scenario involving the reflection of light at a surface. Here's what we can infer from the diagram:

1. Incident Ray (AB): The ray labeled \( AB \) is incident on the reflecting surface \( PQ \) at point \( X \).
2. Reflected Ray (BC): The ray labeled \( BC \) is the reflected ray.
3. Normal (BX): The dashed line \( BX \) represents the normal to the reflecting surface at point \( X \). The normal is perpendicular to the surface at the point of incidence.
4. Angles of Incidence and Reflection: The angles formed by the incident ray and the reflected ray with the normal are crucial for solving the problem.

The task likely involves applying the Law of Reflection, which states:
\[
\text{Angle of Incidence} = \text{Angle of Reflection}
\]

Solution Explanation:

To solve the problem, we need to identify and use the following key components:

#### 1. Identify the Angles:
- Angle of Incidence (\( \theta_i \)): This is the angle between the incident ray \( AB \) and the normal \( BX \).
- Angle of Reflection (\( \theta_r \)): This is the angle between the reflected ray \( BC \) and the normal \( BX \).

#### 2. Apply the Law of Reflection:
According to the Law of Reflection:
\[
\theta_i = \theta_r
\]
This means the angle formed by the incident ray with the normal is equal to the angle formed by the reflected ray with the normal.

#### 3. Geometric Interpretation:
- The incident ray \( AB \) approaches the surface and hits it at point \( X \).
- The reflected ray \( BC \) emerges from point \( X \) such that the angle it makes with the normal \( BX \) is equal to the angle the incident ray \( AB \) made with the normal.

#### 4. Conclusion:
The primary goal is to understand and apply the relationship between the angles of incidence and reflection. If specific angle measurements are provided in the problem (e.g., the angle of incidence), you can directly calculate the angle of reflection using the equality \( \theta_i = \theta_r \).

Final Answer:

The solution to the problem relies on the application of the Law of Reflection. If no specific numerical values are given, the general principle is:
\[
\boxed{\text{Angle of Incidence} = \text{Angle of Reflection}}
\]

If numerical values were provided in the task, they would be used to compute the exact angles. Let me know if additional details or numerical values are available for further computation!
