Reflectance is light incident on the surface of a material that is reflected at an interface. Light not reflected from the sample is absorbed, scattered or transmitted.
Very smooth or shiny, mirror-like surfaces have high specular reflectance, in which the incident light reflects in the same direction. Rough or matte surfaces have diffuse reflectance, where the incident light gets scattered in all directions. Most surfaces exhibit a combination of specular and diffuse reflectance.
