Solution
Correct Answer:
Reflection
The Laws of Reflection state:
- The incident ray, the reflected ray, and the normal to the reflecting surface at the point of incidence all lie in the same plane.
- The angle of incidence (i) is equal to the angle of reflection (r).
- Both angles are measured from the normal to the surface, not the surface itself.
- This applies to both smooth (specular) and rough (diffuse) surfaces.
This easy difficulty physics question is from the chapter optics, covering the topic of reflection law. It appeared in the 2025 exam.
