FAQs on Reflection & Laws of Reflection

1. What is the Law of Reflection?
Ans. The Law of Reflection states that the angle of incidence is equal to the angle of reflection, where the incident ray, the normal line, and the reflected ray all lie on the same plane.
2. How is the angle of incidence measured in reflection?
Ans. The angle of incidence is measured between the incident ray and the normal line to the surface at the point of incidence.
3. What is the difference between regular reflection and diffuse reflection?
Ans. Regular reflection occurs when light rays are reflected uniformly in a single direction, while diffuse reflection happens when light rays are reflected in multiple directions due to the roughness of the surface.
4. Can the angle of reflection ever be greater than the angle of incidence?
Ans. No, according to the Law of Reflection, the angle of reflection can never be greater than the angle of incidence.
5. How does the Law of Reflection apply to various surfaces, such as curved mirrors or water surfaces?
Ans. The Law of Reflection applies to all surfaces, including curved mirrors and water surfaces, where the angle of incidence is still equal to the angle of reflection at each point of reflection.
