Solution

In regular reflection, a parallel beam of incident light is reflected as a parallel beam in one direction; while in diffused reflection, a parallel beam of incident light is reflected in different directions. Regular reflection occurs from a nicely polished reflective surface, while diffused reflection occurs from an irregular surface.

(a) Cinema screen - Regular reflection
(b) Plane mirror - Regular reflection
(c) Cardboard - Diffused reflection
(d) Still water surface of a lake - Regular reflection
