Describe the term diffuse reflection

Question

Describe the term diffuse reflection in detail.

Answer 1

Diffuse reflection is the feature of light reflected from a dull, non shiny surface. The objects illuminated solely by diffusely reflected light show an equivalent light intensity from all the viewing directions. That is, in the diffuse reflection light incident on the surface is reflected uniformly in all directions and is attenuated by an amount dependent on the physical properties of the surface. As light is reflected uniformly in all the directions the perceived illumination of the surface is not based on the position of the observer. Diffuse reflection models the light reflecting properties of matt surfaces that is, surfaces which are rough or grainy that tend to scatter the reflected light in all the directions. This scattered light is termed as the diffuse reflection.
