(a) Polished wooden table
(b) Chalk powder
(c) Card board surface
(d) Marble floor with water spreads over it.
(e) Mirror

Text Solution

Verified by Experts

(a) A regular reflection takes place on a polished wooden table because its surface is smooth.
(b) A diffused reflection takes place on a chalk powder because its surface is uneven.
(c) Cardboard surface has minute irregularities on it, so it will have a irregular reflection.
(d) Marble floor with water spreads over acts as a surface for a regular reflection as it will act like a plane surface.
(e) Mirror has a regular reflection, its surface is also shiny and has smooth surface.
