Reflectance

R

The ratio of reflected radiation to incident radiation on a surface. The suffix (-ance) implies a property of a particular type of surface.
Virtually all remote sensing measurements in the visible range can be converted to reflectance, which is a standard optical property related to the substance or surface from which light is reflected. Because reflectance can be wavelength-specific due to absorption and scattering, reflectance is a key and basic quantity in using remote sensing to determine the identity of anything that reflects light.

Visible (400-700 nm)
