Question:

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

Answer:

Difference between the regular reflection and the diffused reflection are as follows:

                              Regular Reflection

                                  Diffused Reflection

 When all the parallel rays reflected from a plane surface are parallel, the reflection is known as regular reflection.

 When all the parallel rays reflected from the surface are not parallel, the reflection is known as diffused reflection.

 The image formed by the regular reflection is sharp and clear.

 The image formed by the irregular reflection is either faint or  blurred.

 Regular reflection takes place on a smooth surface.

 Irregular reflection takes place on the round surface.

No, diffused reflection does not mean the failure of laws of reflection. The laws of reflection are also followed in diffused reflection.
