oppervlaktesreflectantie

Oppervlaktesreflectantie, often shortened to reflectance, is a fundamental property of a surface that describes how much light it reflects. It is typically expressed as a value between 0 and 1, or as a percentage, where 0 represents perfect absorption (no reflection) and 1 represents perfect reflection (all incident light is reflected). The specific value of reflectance depends on the material's composition, its surface texture, and the wavelength of the incident light.

Different materials exhibit distinct reflectance characteristics. For instance, a highly polished mirror has a very high reflectance across a broad range of visible wavelengths, making it appear bright and reflective. In contrast, a matte black surface has a very low reflectance, absorbing most of the light that strikes it and appearing dark. The color of an object is directly related to its selective reflectance; a red object reflects red light strongly while absorbing other colors.

Reflectance plays a crucial role in various scientific and engineering fields. In remote sensing, understanding the reflectance of different Earth surface features allows scientists to identify vegetation, water bodies, and geological formations. In optics, reflectance is a key parameter in the design of lenses, mirrors, and other optical instruments. In computer graphics, surface reflectance is simulated to create realistic visual representations of objects. The measurement of reflectance can be performed using spectrophotometers and other optical instruments.
