A polished surface is an example of a smooth surface. Hence, reflections from the polished table will be regular.
(b) Chalk powder - Diffused reflection
Chalk power spread on a surface Is an example of an irregular surface. It is not smooth. Therefore, diffused reflection will take place
from chalk powder.
(c) Cardboard surface - Diffused reflection
Cardboard surface is also an example of an irregular surface. Hence, diffused reflection will take place from a cardboard surface.
(d) Marble floor with water spread over it - Regular reflection
Marble floor with water spread over it is an example of a regular surface. This is because water makes the marble surface smooth. Hence, regular reflection will take place from this surface.
(e) Mirror - Regular reflection
Mirror has a smooth surface. Therefore, it will give a regular reflection .
(f) Piece of paper - Diffused reflection
Although a piece of paper may look smooth, but it has many irregularities on its surface. Due to this reason, it will give a diffused reflection.
