What law states angle of incidence equals angle of reflection?Newton's First LawLaw of RefractionLaw of ReflectionKepler's Third Law

Step 1: Identify the Question

The question asks which law states that the angle of incidence is equal to the angle of reflection.

Step 2: Review the Options

1. Newton's First Law: Relates to motion and inertia.
2. Law of Refraction: Relates to the bending of waves when passing through different mediums.
3. Law of Reflection: States that the angle of incidence equals the angle of reflection.
4. Kepler's Third Law: Relates to the orbit of planets.

Step 3: Analyze Each Law

• Newton's First Law does not relate to angles or reflection.
• Law of Refraction deals with refraction, not reflection.
• Law of Reflection directly states that the angle of incidence (the angle between the incoming ray and the normal line) is equal to the angle of reflection (the angle between the reflected ray and the normal).
• Kepler's Third Law pertains to planetary motion and is also irrelevant to this context.

Step 4: Conclusion

After analyzing the definitions and contexts of these laws, it is clear that the Law of Reflection is the correct answer.

Final Answer

Law of Reflection states that the angle of incidence equals the angle of reflection.
