What surfaces reflect light and which do not?
Surfaces that are smooth and shiny, such as mirrors and glass, reflect light. Surfaces that are rough and dull, such as fabric and paper, do not reflect light as effectively. Rough surfaces scatter light in different directions instead of reflecting it.
Does light reflect from all surfaces?
No, not all surfaces reflect light. Surfaces that are smooth and polished, like mirrors, reflect light well. Rough or matte surfaces may absorb or scatter light instead of reflecting it.
Do Rough surfaces reflect light?
Rough surfaces reflect light in a more scattered and diffuse manner compared to smooth surfaces. This is because the irregularities on the rough surface cause light to bounce off in different directions rather than reflecting back uniformly like on a smooth surface.
What is the reflection of light from a rough surface called?
The reflection of light from a rough surface is called diffuse reflection. Unlike smooth surfaces that exhibit specular reflection (reflecting light uniformly in one direction), rough surfaces scatter light in various directions, causing the reflection to be diffused.
Is it true that most paper does not reflect light very well because its surface is somewhat rough?
Yes, that is correct. The rough surface of paper scatters light instead of reflecting it, which causes it to appear dull or absorb light rather than reflecting it effectively. This is why paper is generally not very good at reflecting light compared to smoother surfaces like glass or metal.

Why does light reflect better off of smooth surfaces than rough surfaces?
Light reflects better off of smooth surfaces because the surface is flat and regular, allowing the light waves to reflect uniformly without scattering in different directions. In contrast, on rough surfaces, light scatters in various directions due to the uneven surface, resulting in weaker and less coherent reflection.
What shapes reflect light best the answers?
Shapes with smooth, flat surfaces, such as mirrors or prisms, are best at reflecting light. These surfaces allow light to bounce off of them in a more organized and predictable manner compared to rough or irregular surfaces. The shape of the object can also affect how light is reflected, with concave and convex surfaces influencing the direction of the reflected light.
What materials are bad reflectors of light?
Materials that are dark or absorbent, such as black cloth, wood, or matte surfaces, are bad reflectors of light because they absorb the light instead of reflecting it. Rough or uneven surfaces also tend to scatter light rather than reflect it effectively.
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.
The best absorbers of heat are what kinds of surfaces?
Dark, rough surfaces are typically better absorbers of heat compared to light, smooth surfaces. This is because dark surfaces absorb more light and convert it into heat, while rough surfaces have a greater surface area for heat absorption.
What is the rule used to decide if something can reflect light?
The rule for determining if something can reflect light is that the surface must be smooth and shiny. Rough surfaces scatter light in all directions instead of reflecting it. Smooth and shiny surfaces allow light to bounce off at equal angles, creating a reflection.
What happens when parallel rays hit a rough or bumpy surface?
When parallel rays hit a rough or bumpy surface, the rays reflect in different directions due to the uneven nature of the surface. This causes diffuse reflection, where light is scattered in various directions rather than reflecting in a single direction like with smooth surfaces. This is why we see rough surfaces like sand or paper as not reflecting a clear image.
