reflectance
noun
re·flec·tance
ri-ˈflek-tən(t)s 
: the fraction of the total radiant flux incident upon a surface that is reflected and that varies according to the wavelength distribution of the incident radiation
The basis of this approach is that different materials exhibit unique reflectance and emission properties as a function of wavelength across the electromagnetic spectrum.—
