उत्तर
The laws of reflection hold true for all reflecting surfaces.
Explanation:
The laws of reflection are fundamental principles of optics that describe how light behaves when it hits a surface. These laws state:
- The angle of incidence is equal to the angle of reflection.
- The incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane.
