Reflectance
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 an interface. The reflectance spectrum or spectral reflectance curve is the plot of the reflectance as a function of
wavelength.
