Question

what happens to the rays of light in case of diffuse reflection from a rough surface a parallel incident beam becomes non parallel after reflection .Are the laws of reflection valid here ? give reasons​

Answer 1

Explanation:

law of reflection say that incident ray, reflected ray and normal lie in same plane. And angle of incidence and angle of reflection is equal.

Law of reflection is also valid for rough surface because, when you magnifies the rough surface you see the plane surface at different angle.

when single ray incident on that plane surface (magnified rough surface) it fallow the law of reflection.
