WebReflectance is the ratio of energy reflected to the total energy incident on a body, expressed in percentage. An object appears green because it reflects only wavelengths … 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 of the electronic structure of the material to the electromagnetic field of light, and is in … Zobraziť viac Hemispherical reflectance The hemispherical reflectance of a surface, denoted R, is defined as Spectral hemispherical reflectance The spectral hemispherical reflectance in frequency and … 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 reflection from a body of water is calculated by the Fresnel equations. Fresnel reflection … Zobraziť viac • Bidirectional reflectance distribution function • Colorimetry • Emissivity • Lambert's cosine law • Transmittance Zobraziť viac For homogeneous and semi-infinite (see halfspace) materials, reflectivity is the same as reflectance. Reflectivity is the square of the … Zobraziť viac Given that reflectance is a directional property, most surfaces can be divided into those that give specular reflection and those that give diffuse reflection. For specular surfaces, such as glass or polished metal, reflectance is nearly zero at all angles … Zobraziť viac The generalization of reflectance to a diffraction grating, which disperses light by wavelength, is called diffraction efficiency Zobraziť viac • Reflectivity of metals Archived 2016-03-04 at the Wayback Machine. • Reflectance Data.
