Light rays from an object fall on a surface and get reflected in a completely…

Reflection follows two broad patterns. In regular (specular) reflection, a smooth surface keeps the angle of incidence equal to the angle of reflection for every ray, so the reflected rays stay in a fixed geometric relationship to each other and can converge to, or appear to diverge from, a single point -- this is what produces an image. In diffuse (irregular) reflection, a rough surface reflects each ray at a different angle because the local surface normal changes from point to point; the law of reflection (angle of incidence equals angle of reflection, measured from the local normal at each point) still holds locally, but since neighbouring normals point in different directions, the reflected rays scatter outward with no shared point of convergence or divergence.

Here, the light is stated to be reflected in a completely diffused manner, so every incident ray leaves the surface heading in an essentially random direction relative to the others. Since there is no single point where the outgoing rays meet (a real image) or from which they appear to originate when traced backward (a virtual image), the eye cannot reconstruct a coherent picture of the object from these rays.

• A virtual, same-size image (as from a plane mirror) needs every ray to keep the same fixed angular relationship on reflection -- that orderliness is exactly what diffuse scattering removes.

• A real, enlarged image (as from a converging mirror or lens, with the object placed between the focal point and twice the focal length) needs the reflected or refracted rays to actually meet at a point on the image side of the surface -- random scattering prevents any such meeting point.

• A virtual, enlarged image (as from a magnifying mirror or lens) needs the diverging rays to trace back to one common point behind the surface -- again impossible once the rays scatter with no shared geometry.

So none of these image-forming outcomes can occur; no image is formed. This matches the official CTET January 2021 Paper 2 answer key (Set M, Question 68) and the standard NCERT Class 8 Science treatment of regular versus diffuse reflection.
