What is meant by the idea that a surface may be polished for some wave s and rough for other?
When a surface is said to be polished for some waves and rough for others, it means that the surface selectively reflects or absorbs certain wavelengths of light or other waves based on their properties. The surface may appear smooth and reflective to some wave frequencies, while appearing irregular and absorptive to others. This phenomenon is key in the field of optics and materials science.

Why is it easier to dance on a polished and smooth surface than on a rough surface?
Dancing on a polished and smooth surface is easier because there is less friction between your shoes and the floor, allowing for smoother movements and transitions. On a rough surface, more friction is present, making it harder to glide and pivot, thus hindering your ability to dance fluidly.
Name any 5 smooth and 5 rough surfaces?
smooth:- surface of the mirror , floor of the room when polished , surface of wet soaps,glazed tiles & surface of a oily pot . rough :- soles of shoes , surface of a ply board , unpainted wall, surface of a brick & surface of tyres .
What can smooth out a rough surface?
Sanding the surface with sandpaper or using a sander can help smooth out a rough surface by removing imperfections and creating a more even texture. Applying a coat of primer or filler before painting or finishing can also help to create a smoother surface.
Why your reflection is better in metal when polished the surface?
When a metal surface is polished, it becomes very smooth and flat, resulting in less scattering of light. This causes the light to be reflected uniformly, giving a mirror-like appearance with high reflectivity. In contrast, a rough surface scatters light in different directions, resulting in a dull reflection.
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.
Why do you not see your reflection when you look at a building made of rough white stone?
Because the surface isn't polished enough to reflect. If it was polished marble or any other polished stone, you might be able to see a reflection. It would be equivalent to getting a reflection from rough concrete, it wont happen. The rough surface of stone or concrete scatters the light reflecting off of it.
Difference between flamed granite and polished granite?
The difference between flamed and polished granite is following : Flamed : The Flaming is a type of finishing to change the surface of granite by burning it by flames. This procedure change the surface in some type of rough finishing. Polished : The polishing is a finishing to change the rough surface to smooth and glossy finishing. This process is done by polisher.
Why is it easier to dance on a polished and smooth surface than on a rough surface?
Dancing on a polished and smooth surface is easier because there is less friction between your shoes and the floor, allowing for smoother movements and transitions. On a rough surface, more friction is present, making it harder to glide and pivot, thus hindering your ability to dance fluidly.
Is aluminum smooth or rough?
Aluminium is rough
What is meant by the idea that a surface may be polished for some waves and rough for others?
This idea refers to how different types of waves interact with surfaces. Waves may reflect or pass through surfaces based on their properties. For example, a smooth surface may reflect light waves effectively like a mirror, while a rough surface may scatter sound waves, making them less distinct.
How can steel wool be used in wood finishing techniques to achieve a smooth and polished surface?
Steel wool can be used in wood finishing techniques to achieve a smooth and polished surface by gently rubbing it on the wood surface in between coats of finish. The steel wool helps to smooth out imperfections and remove any rough spots, resulting in a more polished and even finish.
Name any 5 smooth and 5 rough surfaces?

What fraction of sunlight is reflected by a surface?
The answer varies from one surface to another. A highly polished mirror will reflect almost all whereas a rough black body will reflect very little.
How does gneiss feel?
A fractured surface--rough. A polished or worn surface--smooth.

What happens when you try to walk on a smooth polish surface wearingbrand new shoes?
Depends on the surface of your sole on the shoe. Polished leather or rough rubber-sole! Leather: You slip. Rubber brobably make marks on the surface
