Reflection of Light Rays on a Rough Surface
When light rays strike a rough surface, the phenomenon that occurs is known as reflection. This is because the surface is not flat and causes the light rays to scatter in different directions.

Irregular Reflection
In the case of a rough surface, the light rays do not reflect uniformly in a single direction. Instead, they bounce off the surface in various angles, leading to what is known as irregular reflection.

Diffuse Reflection
The reflection of light rays on a rough surface is called diffuse reflection. In this process, the light rays are reflected in multiple directions due to the uneven surface, unlike in smooth surfaces where the reflection is more uniform.

Scattering of Light
When light rays strike a rough surface, they scatter in different directions due to the irregularities of the surface. This scattering results in the diffuse reflection of light.

Enhanced Visibility
The phenomenon of diffuse reflection on rough surfaces plays a crucial role in enhancing visibility. For example, matte surfaces such as walls, paper, or clothing reflect light diffusely, reducing glare and providing a more comfortable viewing experience.
In conclusion, when light rays strike a rough surface, they undergo diffuse reflection, scattering in various directions due to the irregularities of the surface. This phenomenon of reflection on rough surfaces contributes to enhanced visibility and reduced glare in our everyday surroundings.
