Question

Define laws of reflection of light

Answer 1

Definition of law of reflection

: a statement in optics: when light falls upon a plane surface it is so reflected that the angle of reflection is equal to the angle of incidence and that the incident ray, reflected ray, and normal ray all lie in the plane of incidence

Answer 2

"If or when a light ray is reflected on a smooth surface or a mirror , the reflected ray, and the normal to the smooth surface  ( or to the surface of the mirror) all lie in the same plane, and the angle of reflection  is equal to the angle of incidence"
