Answer:
the principle that when a ray of light, radar pulse, or the like, is reflected from a smooth surface the angle of reflection is equal to the angle of incidence, and the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane.
The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
