Question

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

Answer 1

S.No.	Regular reflection	Diffuse reflection
1.	In regular reflection, the reflected rays are parallel to each other.	In diffused reflection, the reflected rays are not parallel to each other.
2.	Regular reflection occurs from a nicely polished regular reflective surface.	It occurs from a diffused or irregular surface.
3.	All the reflected rays are parallel.	The reflected rays are not parallel.
4.	Reflected rays are in one direction.	Reflected rays are scattered in different directions.

1. Diffused reflection also follows the laws of reflection.
2. In diffused reflection rays are not parallel to each other but follow the laws of reflection.
3. Because in diffused rays, the angle of incidence is equal to the angle of reflection and incident ray, reflected ray and normal, all lie on the same plane.
4. Hence, diffused reflection does not violate the laws of reflection.
