law of reflection

Question

Law of reflection states angle of incidence equals?

RankGuru · Accepted Answer

1. **Laws of Reflection**: 
   - The incident ray, the normal to the reflecting surface at the point of incidence, and the reflected ray all lie in the same plane.
   - The angle of incidence ($	heta_i$) is exactly equal to the angle of reflection ($	heta_r$).
2. **Measurement**: Both angles are measured from the **normal** (the line perpendicular to the surface).
3. **Application**: This law holds for all types of reflecting surfaces, whether plane or curved (like spherical mirrors).
4. **Conclusion**: $	heta_i = 	heta_r$.
