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 number as … 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 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 The generalization of reflectance to a diffraction grating, which disperses light by wavelength, is called diffraction efficiency.

In real life terms what this means is that light is reflected off non-shiny surfaces such as the ground, walls, or …
WebReflectivity is the capacity of an object to reflect solar radiation. It is described as a function of radiation wavelength and is determined by the physical composition of the object. The … WebThe amount of light reflected by an object, and how it is reflected, is very dependent upon the smoothness or texture of the surface.
