How is the reflection of light by a mirror different from its reflection by other surfaces?
Wiki User
∙ 12y ago
Reflection of light by a mirror is regular and obeys the law of reflection, resulting in a clear and specular image. On the other hand, reflection by other surfaces can be irregular, diffuse, and often results in a blurry or scattered image due to the uneven nature of the surface.

Why do rough surfaces appear dull?
Rough surfaces appear dull because they scatter light in different directions, resulting in multiple reflections and diffused light. This diffuse reflection does not create a uniform, mirror-like reflection that is characteristic of smooth surfaces, leading to a dull appearance.
Does specular reflection occur when it hits a dull surface?
No, specular reflection occurs when light hits a smooth and shiny surface, such as a mirror. On the other hand, dull surfaces scatter light in different directions, which is known as diffuse reflection.
How does light reflect on different surfaces?
Light reflects differently on different surfaces based on their texture, color, and material. Smooth and shiny surfaces like glass or metal tend to reflect light more clearly and create a mirror-like reflection. Rough or matte surfaces like paper or fabric scatter light in various directions, creating a diffuse reflection. The color of the surface also affects how it reflects light, with lighter colors reflecting more light than darker colors.
What reflection comes from rough surfaces?
Rough surfaces tend to scatter light rays in various directions, resulting in diffuse reflection. This means that the light is reflected irregularly and does not create a clear, mirror-like image, but instead creates a softer, less defined reflection.
Why is a mirror a good reflector?
A mirror is a good reflector because its surface is smooth and polished, allowing light to bounce off it in a regular pattern. This results in a clear and sharp reflection of images. Mirror surfaces are designed to minimize light absorption and maximize light reflection, making them efficient reflectors.

No, the color of a mirror does not affect it's reflection of light.

Can a mirror cause diffuse reflection?
Yes, a mirror can cause diffuse reflection. If the surface of the mirror is not perfectly smooth or if the incident light is scattered in different directions upon reflection, it can lead to diffuse reflection instead of the usual specular reflection associated with mirrors.
Occurs when light is reflected in many directions from a rough surface?
Diffuse reflection occurs when light hits a rough surface and scatters in different directions, instead of reflecting at a single angle like in regular, or specular, reflection. This phenomenon is responsible for creating a matte appearance on surfaces that do not produce a clear, mirror-like reflection.
When light hits a mirror?
When light hits a mirror, it undergoes specular reflection, meaning it bounces off the mirror at the same angle it hits it. This reflection allows us to see our reflection in the mirror.
Is a regular reflection the reflection of light from a rough surface?
No, regular reflection is the reflection of light from a smooth surface where all light rays reflect in a parallel manner. Reflection from a rough surface results in diffuse reflection, where light rays scatter in different directions.
Why don't rough shiny surfaces don't make good mirrors?
The angle of reflection and coherence of the light coming off a surface relies on the surface being smooth to keep the reflected photons returning at very close to the same pattern as it hits the mirror. A rough surface reflects the photons at many different angles - there is some reflection but in general it is so degrade we can barely see a reflection. The law of law of reflection says that for smooth surfaces, the angle of reflection is the same as the angle of incidence. If the light hits at many different angles, the light returned comes at many different angles; not a good thing for perceiving a reflection.
