Another way to interpret this is that the reflectance is the fraction of electromagnetic power reflected from a specific sample, while reflectivity is a property of the material itself, which would be measured on a perfect machine if the material filled half of all space. Zobraziť viac The reflectance of the surface of a material is its effectiveness in reflecting radiant energy. It is the fraction of incident electromagnetic power that is reflected at the boundary. Reflectance is a component of the response … Zobraziť viac Given that reflectance is a directional property, most surfaces can be divided into those that give specular reflection and those that give Zobraziť viac The generalization of reflectance to a diffraction grating, which disperses light by wavelength, is called diffraction efficiency. Zobraziť viac Hemispherical reflectance The hemispherical reflectance of a surface, denoted R, is defined as Spectral hemispherical reflectance The spectral … Zobraziť viac For homogeneous and semi-infinite (see halfspace) materials, reflectivity is the same as reflectance. Reflectivity is the square of the magnitude of the Fresnel reflection coefficient, which is the ratio of the reflected to incident electric field; as such the … Zobraziť viac Reflection occurs when light moves from a medium with one index of refraction into a second medium with a different index of refraction. Specular … Zobraziť viac • Bidirectional reflectance distribution function • Colorimetry • Emissivity Zobraziť viac WebOverview.

This ratio can be useful to discriminate broad classes of vegetation. Croplands have appeared as lighter (brighter) tone and forests appeared as dark tone. dmn2990udj-7a
