Hemispherical pattern

Hemispherical attenuation coefficient: μ: m −1: Radiant flux absorbed and scattered by a volume per unit length, divided by that received by that volume. Spectral hemispherical attenuation coefficient: μ ν or μ λ: m −1: Spectral radiant flux absorbed and scattered by a volume per unit length, … 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 surfaces, such as glass or polished metal, reflectance is nearly zero at all angles … Meer weergeven The generalization of reflectance to a diffraction grating, which disperses light by wavelength, is called diffraction efficiency. Meer weergeven Hemispherical reflectance The hemispherical reflectance of a surface, denoted R, is defined as Spectral hemispherical reflectance The spectral hemispherical reflectance in frequency and spectral hemispherical reflectance … Meer weergeven 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 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.
