Q.2 Differentiate between regular and diffused reflection. Does diffused reflection mean the failure of the laws of reflection?

Regular Reflection

(i) All the reflected rays are parallel to each other.
(ii) Regular reflection takes place when the reflection occurs on a smooth and polished surface.
(iii) Reflected rays travel in one direction.

Diffused reflection

(i) The reflected rays are not parallel to each other.
(ii) Diffused reflection takes place when the reflection occurs on a rough surface.
(iii) Reflected rays travel in scattered directions.

Diffused reflection doesn't means the failure of the laws of reflection. As it occurs only when the reflecting surface is rough and has irregularities, so it doesn't violate the laws of reflection.
