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 ?
Answer: D
No image will be formed.
An image forms when reflected rays from each point of the object stay together in an orderly way, as from a smooth mirror (regular reflection). In completely diffused reflection, from a rough surface such as paper or a wall, parallel rays are scattered in all directions, so they do not meet or appear to meet at any point.
The other options describe images that need regular reflection. A virtual image of the same size is what a plane mirror forms. Real enlarged and virtual enlarged images are formed by concave mirrors. A diffusing surface forms none of these.
