(A) Regular reflection of light takes place.
When a ray of light fall on a surface and angle of incidence is equal to the angle of reflection (law of reflection hold true) we called regular reflection.
In case of polished wooden table law of reflection hold true because the surface is polished (smooth). Thus there will be a regular reflection.
(B) Diffuse reflection of light takes place.
When a ray of light fall (strike) on the surface of Chalk powder, reflected ray get scatted in a different direction with a different angle. So, the law of reflection doesn’t hold true. Thus, diffuse reflection.
(C) Diffuse reflection of light takes place.
Surface of cardboard in not smooth. Law of reflection doesn’t hold.
(D) Regular reflection of light takes place.
In mirror (any type of mirror can be plane or concave or concave) law of reflection hold. So regular reflection takes place.
(E) 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.
(F) Regular reflection of light takes place.
The surface of the marble floor is covered with water and on the water surface law of reflection hold true.
Additional information:-
When the light fall on the surface of the water some part gets reflected and some part get refracted.
Both laws of reflection and law of refraction hold true for water.
