Reflectivity of a material
WebApr 6, 2024 · Reflectivity is defined as the property of a material to reflect the light or radiation. It is a measurement of reflectance irrespective of the thickness of a material. … WebFeb 9, 2024 · The reflectivity of metal surfaces is an important consideration in the built environment because the relative reflectivity of metals is typically much greater than surrounding surfaces. It is often desired to have a reflective metal surface—not necessarily blindingly bright but reflective enough that it catches the eye.
