Briefly mention, which of the following will cause regular reflection of light and which diffuse reflection of light.

Paper

Diffuse reflection of light takes place.


The surface of paper is not smooth. Law of reflection doesn’t hold.


Additional information:-


If you are thinking the paper is smooth than just remember - it is impossible to write on a smooth surface. Smooth surface means no friction. So, on the surface of mirror, we can consider as friction = 0. If the paper has zero friction that implies we cannot write on the paper.
