Mark the statement which is true for Diffused reflection.
A). Diffused reflection is due to failure of laws of reflection
B). It is caused due to irregularities in the reflecting surface
C).when the incident light is diffused in nature it causes diffused reflection
D). All are true

Hint: Diffuse reflection is the reflection of light from a surface in which an incident ray is reflected at several angles rather than just one, as in specular reflection. The Lambertian reflectance of an illuminated ideal diffuse reflecting surface is equal brightness from all directions in the hemisphere surrounding the surface.

Complete Step By Step Answer:
The correct answer is option B, it is caused due to irregularities in the reflecting surface.
Light falling on a surface may be reflected directly or diffusely. Direct reflection, like a mirror, is specular. Diffuse reflection might be uniform or preferential: brightness is identical in all possible directions in the former; maximum in specific directions in the latter. When a light beam falls at a specific angle onto an extremely smooth opaque surface, nearly all of the light is reflected off the interface in a restricted range of directions. The surface would be considered highly shiny. Because light reaches the surface at many distinct angles, the interface of a highly rough surface will tend to reflect light at many different angles. The reflected light is so diffused that the observer cannot view images of the surroundings.

Note:
A surface made of a non-absorbing powder, such as plaster, or fibres, such as paper, or a polycrystalline substance, such as white marble, reflects light diffusely and effectively. Many popular materials have a combination of specular and diffuse reflection.
