Question

In case of diffused reflection

Answer 1

Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection. ... Many common materials exhibit a mixture of specular and diffuse reflection. 

Answer 2

Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scatteredat many angles rather than at just one angle as in the case of specular reflection. An idealdiffuse reflecting surface is said to exhibit Lambertian reflection, meaning that there is equal luminance when viewed from all directions lying in the half-space adjacent to the surface.
