Rough surface look dull. Dry surfaces room pale and washed out. Sealed surfaces can be rich, and also polished surfaces room deep and shiny. Us all know this, yet what is going on?Light reflects off surfaces, and also what an object looks prefer depends upon the material’s surface characteristics. Few of the light is reflected, part is scattered and also the remainder is absorbed, so us see various things depending on how lot light is reflect from the surface and also how much is scattered. The shade depends upon what is absorbed.

You are watching: A shiny surface reflects less light than a matte surface

A highly polished winter reflects many of the light in one direction. Almost every one of the light rays room reflected in a parallel orientation and nearly none room scattered. Because the light is reflected there is no scattering, the picture is clear and also in focus. This is dubbed “specular reflection,” and the term often is used to explain the highlight visible ~ above a brightly lit object and the glare watched from light shining on a very shiny surface.

Rough, translucent or transparent objects scatter many of the incoming light in a “diffuse reflection,” with little or no glare native specular reflection.When concrete is wet, sealed or highly polished, over there is more specular reflection than diffuse reflection. At certain viewing angles all we check out is glare or the picture of the irradiate that’s illuminating the surface. At various other angles, no in line v the path of the reflected light rays, we don’t see any type of glare – every that’s clearly shows is the color of the surface.When concrete is dried or is no polished, almost all of the irradiate is scattered in diffuse reflection and also the surface seems pale, washed out or dull. That’s because there’s no concentrated reflection of the irradiate source. The incoming light is scattered and overwhelms the reflected color. The net result is that the surface shows up light, dull and also washed the end no matter what edge the concrete is perceived from.

This test slab demonstrates how various sealers leave different-looking finishes ~ above the exact same concrete.
Sealers have the right to fill in microscopic surface roughness, reducing the lot of diffuse reflection and increasing the specular reflection. This is why concrete that’s sealed or is wet appears darker and richer in color. It likewise explains why shiny surfaces have glare.

The apple is red, but since the surface is glossy, the light resource is visible together a white highlight.With glowing surfaces, much more of the white light from one illumination source reflects turn off the object. What diffusive reflection occurs shows us the shade of the object. Every the light is impacted by the color of the object, but the soot of the specular reflection on smooth, wet or shiny surface overwhelms the diffusive portion.

A surface ar sealed through a matte complete has part specular have fun that shows the color and some diffuse reflection.

Generally the glossier the surface, the deeper and richer the color appears. Conversely, with a flatter and less glowing surface, the color tends to look an ext washed out and also dull. To compare a matte and also glossy surface ar of exactly the same color, the matte surface has sufficient scattered white light to dilute the reflect color, making the overall appearance an ext washed out and also lifeless.
