When a rays of light falls on an uneven object or surface to they get scattered in all directions then how we can see the rough or uneven object or surface?
Irregular reflection is the reflection of light rays when they meet ( fall on ) a rough ( non-uniform ) reflecting surface , where the incident light rays are reflected in different directions .
When a beam of parallel light rays is scattered in all directions , So , the parallel rays incident on the surface will reflect in different directions , and it is called irregular or diffuse reflection .
Irregular reflection or diffused reflection takes place when the light rays are incident on a surface like a wall , the wood , a leaf of a tree , a piece of leather , a piece of paper or a piece of wool , which are not smooth or polished , so , the different portions of the surface reflect the incident light rays in different directions .
There is no definite image formed , but the surface becomes visible , It is commonly known as scattering of light , and diffused reflection makes non-luminous objects visible .
Not all the light rays which hits an object are reflected , Some of the incident light rays are absorbed ,The brightness of an object depends on the intensity of the incident light rays and also on the reflectivity of the object .
