Answer:
C
Explanation:
The definitions for the angle of incidence and angle of reflection are the following:
- The angle of incidence is the angle between the direction of the incoming ray and the normal to the surface
- The angle of reflection is the angle between the direction of the reflected ray and the normal to the surface
Therefore, in the picture attached:
- B is the angle of incidence
- C is the angle of reflection
The law of reflection states that the angle of reflection is equal to the angle of incidence.
