According to the laws of reflection, the angle of reflection equals:
AThe angle of incidence
BTwice the angle of incidence
CHalf the angle of incidence
DThe angle of refraction
Answer & Solution
Correct answer: A. The angle of incidence
1. The first law of reflection states i = r.
2. Both angles are measured from the normal at the point of incidence.
3. This law applies to plane and curved reflecting surfaces alike.
