CoachWhen light reflects off a rough surface, the reflected light scatters in different directions due to the irregularities on the surface. This causes diffuse reflection, where the light is reflected in multiple angles rather than a single angle like in smooth, specular reflection. This creates a matte or non-glossy appearance.
think of the light as a stream of water, now lets say your "smooth surface" is glass the light will bounce off the glass with no problem now lets say you have rocks for your "rough surface" the light will not as easily bounce off of them because they are rugged. there fore the light fragments bounce off of the "rough surface" .
The surface of rough surface is in random order, in lay person's words, the surface is not a straight on as the polished one. As there are a lot of rays, each ray cannot make the same angle of incidence with the same resulting in the difference in angle of reflection. Hence the image is destroyed. It also depends on the roughness of the surface. The rougher the surface is, the more the image of the object will be destroyed.
More information:
The rough surface is actually a collection of many surfaces, randomly angulated and distributed. Most of the incident light is reflected in unfocusable, unpredictable (random) directions. The polished surface, while having a slightly randomized (not perfect) surface, reflects most of the incident light in a relatively predictable and focusable direction.

Does light bounce off evenly rough surfaces?
No, light does not bounce off evenly rough surfaces. When light hits a rough surface, it reflects in many different directions due to the irregularities on the surface, leading to diffuse reflection. This is why rough surfaces appear to scatter light in various directions.
How is light reflected on rough surface?
Light is reflected on a rough surface in many directions due to the uneven surface structure. Each small section of the rough surface reflects light independently, leading to diffuse reflection instead of the regular reflection seen on smooth surfaces. This is why rough surfaces appear matte or less glossy compared to smooth surfaces.
When light reflects off a rough surface it travels together in a different direction True or False?
True. When light reflects off a rough surface, the reflection is diffuse, meaning the light rays scatter in different directions. This is in contrast to a smooth surface where the reflection is more specular, and the light rays travel in a predictable direction.
What kind of surface reflects light unevenly?
A rough or irregular surface reflects light unevenly, causing it to scatter in different directions. This can create a diffuse reflection where the light is not reflected uniformly, unlike a smooth and polished surface that provides a clear and regular reflection. Examples include frosted glass, textured walls, or rough metal surfaces.
How does the field mirror affect the reflection of light?
The mirror's surface smoothness affects how light reflects off of it. A smooth surface reflects light in a clear and organized manner, creating a sharp image. A rough surface scatters light in different directions, resulting in a blurry or distorted reflection.
