Reflection of Light What is Reflection of Light?
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 is directional and therefore does not contribute significantly to albedo which … See more 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 See more 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 … See more The generalization of reflectance to a diffraction grating, which disperses light by wavelength, is called diffraction efficiency See more • Reflectivity of metals Archived 2016-03-04 at the Wayback Machine. • Reflectance Data. See more Hemispherical reflectance The hemispherical reflectance of a surface, denoted R, is defined as Spectral hemispherical reflectance The spectral … See more 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 … See more • Bidirectional reflectance distribution function • Colorimetry • Emissivity • Lambert's cosine law See more Web3. Black has the lowest reflectivity. 4.
