reflectivity

(ˌriːflɛkˈtɪvɪtɪ)
n
1. (General Physics) physics a measure of the ability of a surface to reflect radiation, equal to the reflectance of a layer of material sufficiently thick for the reflectance not to depend on the thickness
2. Also called: reflectiveness the quality or capability of being reflective
