Angle of incidence:The angle of incidence is equal to the angle formed by an incoming ray before it hits a reflecting surface.
Law of Reflection: The law states that when light reflects off a smooth surface, such as glass or water, it follows specific rules - namely, that 'the incident ray, reflected ray, and normal all lie on one plane, and the angle of incidence is equal to the angle of reflection.'
Reflecting surface: A reflecting surface is any smooth surface that can bounce back or reflect light, such as a mirror or polished metal.
