WebAlbedo is the proportion of incident light that is reflected away from a surface.. Diffuse reflection is the reflection of light in many directions, rather than in just one direction like a mirror (specular reflection).. In the case of ideal diffuse reflection (Lambertian reflectance), incident light is reflected in all directions independently of the angle at which it arrived.
