When 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.
Light reflects in an uneven manner.This uneven reflection is the reason for our perfect visualization of total cinema in the theatre
When light hits a rough surface it is scattered according to the refractive index of the surface. The rougher the surface, the duller that it will seem.
Then you can see the surface, but you can't see your face in it.

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.
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.
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.
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.
When a beam of light strikes a rough surface it reflects at?
different angles due to the uneven surface, causing diffuse reflection.
Differentiate regular reflection from diffuse reflection?
Regular Reflection= Happens when light reflects off a smooth surface. Diffuse Reflection= Happens when light reflects off a rough surface. Reflection= The bouncing of waves, off a surface or and object
What does light do when it strikes a surface that is not smooth?
When light strikes a rough surface it reflects in essentially random directions.
What happens when light hits a rough surface?
when light hits a rough surface it scattters.
Why does a rough surface reflect light in many directions?
It reflects in different directions because its rough, there is many sides so the light reflects of the sides causing it to reflect in different directions.

When a beam of light strikes a rough surface it reflects at?
different angles due to the uneven surface, causing diffuse reflection.
What are the 2 kinds of reflection?
The two kinds of reflection are regular reflection, where light reflects off a smooth surface at the same angle it hits it, and diffuse reflection, which occurs when light reflects off a rough surface in many different directions.
What type of surface reflects light the best?
A smooth and flat surface, such as a mirror or polished metal, reflects light the best because it provides a uniform and regular surface for light to bounce off of, resulting in minimal scattering. Rough or uneven surfaces tend to scatter light in multiple directions, reducing the amount of light that is reflected.
What is the property that reflects light?
The property that reflects light is called reflectivity. This is the measure of how well a surface reflects light and is often described in terms of its reflectance or albedo. Smooth, shiny surfaces tend to have high reflectivity, while rough or dark surfaces have low reflectivity.
