Reflectance table
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. 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 Zobraziť viac The generalization of reflectance to a diffraction grating, which disperses light by wavelength, is called diffraction efficiency.
