What is diffuse reflection?
Diffusion reflection is a properties of light to scattering when it reflects the surface. The light travels in a straight line, and when the object hits, its expected primary angle of reflection is called a mirror reflection. In addition, light is also reflected in all possible angles and directions. The degree or size of this scattered reflection depends on the characteristics of reflecting substances and surfaces.
Some surfaces, such as a highly polished metal mirror, reflect the light of almost 100% specular efficiency. Other surfaces, such as the surfaces of some crystals or liquids, can most or all pass through the surface and medium. Most objects of the world, including the above examples, reflect light both separately and diffuse to different levels. Diffusion reflection is the primary feature of light that allows human eyes to be seen by an object.
The main determinant of the reflection is the absorption of the surface of the surface. Polished surfaces such as white Marble Stone, or randomly irregular paper fibers, reflect diffuse light with almost the same efficiency. BlackObjects tend to absorb more light. Some naturally occur and people do things that emit light and overcome any diffuse reflection from their surface to distinguish them as objects.
The light is absorbed and reflects the surfaces in Nano. Visible light, from purple to red, has a wavelength of 380 to 780 nanometers (Nm). Surfaces with molecular structure sympathetic with a given wavelength reflect it. Others will go through it until the beam encounters the reflective surface below it. On this scale, all surfaces are to some extent irregular.
The color of the object is determined by its scattered reflection. Specular reflection, such as the sparkling peaks of the sculptural form of the car, is almost 100% of the light source. The oblique light beams from the rest of its body color are partially absorbed and in all directions, only narrower wavelengths such as cherry red, including admirer's eyes, reflect.
Three types of materials do not have good diffuse reflectance. They include molecular compact substances such as metals that do not allow to pass light. In this category are also substances such as gases and glass with free molecular structures that allow almost all light.
In addition, very simple or very complex crystalline structures absorb light and rather refract it with its surface rather than reflect. This category includes diamonds, salt and hard shell or scales of some insects. Diffusion reflection was also used as a term of photographic techniques to discourage a light source on a subject for more uniform, less directional lighting.
