Law of reflection states angle of incidence equals angle of:

RankGuru · Accepted Answer

The Laws of Reflection state:
1. The incident ray, the reflected ray, and the normal to the reflecting surface at the point of incidence all lie in the same plane.
2. 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.
