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 reflection coefficient can be expressed as a complex … Meer weergeven 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 … Meer weergeven 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 … Meer weergeven The generalization of reflectance to a diffraction grating, which disperses light by wavelength, is called diffraction efficiency. Meer weergeven • Bidirectional reflectance distribution function • Colorimetry • Emissivity • Lambert's cosine law • Transmittance Meer weergeven Hemispherical reflectance The hemispherical reflectance of a surface, denoted R, is defined as Spectral hemispherical reflectance The spectral … Meer weergeven 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 … Meer weergeven • Reflectivity of metals Archived 2016-03-04 at the Wayback Machine. • Reflectance Data.
