Here's why it happens:

* Rough surfaces: Unlike smooth surfaces like mirrors, rough surfaces have irregularities and bumps at the microscopic level.

* Irregular bouncing: When light rays hit these bumps, they are scattered in many different directions.

* Diffuse reflection: This scattering of light is called diffuse reflection, and it results in a blurred or scattered image.

Examples of diffuse reflection:

* Light reflecting off a piece of paper.

* Sunlight scattering off a wall.

* Light bouncing off a rough road surface.

Contrast with specular reflection:

In specular reflection, light rays hit a smooth surface and bounce back at a predictable angle. This is why mirrors reflect images clearly.
