Light rays from an object fall on a surface and get reflected in a completely diffused manner. What can you say about the nature of image of the object ?

Correct Answer: No image will be formed.

Explanation:

When light rays from an object fall on a smooth, highly polished surface (such as a plane mirror), regular or specular reflection takes place. In regular reflection, parallel light rays remain parallel after reflection, meeting at a definite point (or appearing to diverge from a definite point) to form a clear image.

However, when light rays fall on a rough or irregular surface, diffuse reflection occurs. In diffuse reflection, the light rays are reflected in random and scattered directions rather than in a parallel beam. Because the reflected rays do not converge to a single point or appear to originate from a single point of origin, regular intersection of reflected light is lost.

As a result of this completely scattered/diffused reflection, light rays fail to construct a definite pattern, and hence, no image of the object is formed on such a surface.
